QUESTION: If a baseball and bat costs \$1.10, and the bat costs \$1.00 more than the ball, how much does the ball cost?

if the ball costs 10 cents and the bat is \$1 more than the ball, then the bat is \$1.10 and the two combined cannot be \$1.10

I don't think you were supposed to say that, -out loud I mean :eek:

edit; -(for lil' & peregrine below) -okay, if the ball is .05 -and the bat is 1.05...-then the bat is one dollar more than the ball -and combined they are 1.10, -thats me story and I'm sticken to it:p

Okay, I just remembered an African reasoning/intelligence test...-devised to show how utterly clueless the 'western' world is.

It consists of four questions;

1. How do you put an giraffe into a refrigerator?

The correct answer is: Open the refrigerator, put in the giraffe, and close the door. -This question tests whether you tend to do simple things in an overly complicated way

okay, ready?..-Question 2: How do you put an elephant into a refrigerator?

-Did you say; -Open the refrigerator, put in the elephant, and close the refrigerator?

-nope, totally wrong....The correct answer is; Open the refrigerator, take out the giraffe, put in the elephant and close the door.
-this question tests your ability to think through the reprecussions of your previous actions

Question 3; The King of the Lion's -("lion king", -if you will :D) is hosting an animal conference. All the animals attend -except one. Which animal does not attend?

Correct answer; The elephant...you dumba-ss!! -he's stuck in the fricken fridge! -or, I mean...-*kudos* -if you got it :)

-Okay, Last question; There is a river you must cross but it used by crocadiles, and you do not have a boat. How do you manage it?

-Correct answer; -you swim across...the crocadiles are at the animal conference. Do you feel dumb yet? :p

heh, heh... it doesn't take into account the part about "the bat costs \$1.00 more than the ball". The trick here is that there's two variables, so you need to have two equations.

have you ever been in Africa?
I've been to Keeenya. Went on one of those eco-safari trips where they put you in a cage and show you off to the animals. The truck we were in had all these giant holes on the side. I asked the guide what they were... he said that they were from the rhinos. When you wander into their territory in a grey/brown truck, it must look very much like some large animal to the rhinos. So they charge and attack the truck. I guess the rhinos figured out the best way is to attack the soft side & underbelly of their targets. I think impaling an intruder on the side isn't very sporting and doesn't give them much of a chance.

Anyway, we didn't see any rhinos on that day. But personally, I think they have the rhinos trained specifically to attack the trucks to give the tourists a more exciting journey. In todays modern society, everyone wants to get paid, even rhinos... ;)

He tricked some of you out of 10 cents. Now imagine if he fuzzy-numbered you out of a lot more. :)

the question says that a baseball (not plural) and a bat cost 1.10. if the baseball (not plural) actaully costs 5 cents, isn't the question faulty?

edit: thought about it again. yes the question is faulty, because it's using the word cost twice. it would be better posed as "a baseball and a bat sells for 1.10, and the bat costs 1.00 more than the ball." if you take it literally then the ball has to be 10 cents.

An old man and his son are out hiking. They have an accident and the old man dies. But his son survives.

They rush him to hospital, and when they get there the doctor looks down and says, "I can't operate on this boy, he's my son!"

How is this possible?

Also the strange idea that a doctor can not operate on or otherwise treat a relative is garbage. Of course there are a lot of crappy doctors and dentists out there that very likely would refuse to work on their own family members, knowing htat just about anyone else would provide better care.

QUESTION: If a baseball and bat costs \$1.10, and the bat costs \$1.00 more than the ball, how much does the ball cost?

That's easy.

So the ball is a dollar more than the ball, and together the are \$1.10

x + (1 + x) = 1.10 (where x is the ball)

Accounting for an average sales tax

x * 1.06 + (1 + x) * 1.06 = 1.10

and calculating in depreciation over standard three years (assuming a 20% residual, of course)

((x * 1.06) - .2* (x * 1.06))/3 + ((1 + x * 1.06) - .2*(1 + x*1.06))/3 = 1.10

Then allotting for insurance costs for said bat and ball on a 12 year schedule (average life expectancy of sporting equipment) and amatorizing any leveraged debt over the same period (assuming current rates) and refactoring in commonly available tax deductions (federal only) we are at:

(((x * 1.06) - .2* (x * 1.06))/3)/1.333^9 + SQR(((1 + x * 1.06) - .2*(1 + x*1.06))/3/x~y)) / 12^19 = 1.10

Solving for x, the ball costs \$700 in accounting fees (not including legal review).

He's a priest. And refers to everyone euphemistically as "my son".

And always refuses to operate on anyone.

Because he's not really a doctor.

Tim, the answer is: The ball is 5 cents. for the bat to be a dollar more than the ball it has to be thus Bat \$1.05 - Ball\$0.05 = Difference \$1.00. Ergo, the bat is one dollar MORE than the ball. Simple.

BeauFoster
10-12-05, 11:42 AM
\$1.05 (bat) + \$.05 (ball) = \$1.10 total price for both
\$1.05 (bat) - \$.05 (ball) = \$1.00 difference in bat and ball

It's one baseball.

One ball at .05, one bat at 1.05.

10-12-05, 12:01 PM
oops. thanks.

here is where i went wrong. i ended up with 2x=.10, and x=.05. that of course is the right answer, but the 2x part was making me think of more than one ball.

basically if i had plugged .05 into the orginal equation (1+.05)+.05=1.10, i would have gotten 1.10=1.10. i feel dumb now.

Let the value in parentheses be the price of the baseball as it is 1 dollar more then the ball.

x + (1.00 + x) = 1.10
2x + 1 = 1.1
2x -1 = 1.1 - 1
2x = .1
x = .05

.05 + (1.0 + .05) = 1.10
.05 + 1.05 = 1.10

2x + 1 = 1.1
2x -1 = 1.1 - 1
2x = .1
x = .05

.05 + (1.0 + .05) = 1.10
.05 + 1.05 = 1.10

that's exactly how i went about it, except i stopped before the last two lines at x=.05. i then assumed (incorrectly) that 1+2x=1.10. which is crazy if you think about it, because the original equation was different. gotta watch those parenthesis.

basically if i had plugged .05 into the orginal equation (1+.05)+.05=1.10, i would have gotten 1.10=1.10. i feel dumb now.Well, it's easy if you set up two equations to satisfy the two-part puzzle:

1. "If a baseball and bat costs \$1.10", has this equation:

ball + bat = 1.10

2. "and the bat costs \$1.00 more than the ball," has this other equation:

bat = ball + 1.00

3. to solve "how much does the ball cost?", you combine the two equations

ball + bat = 1.10
bat = ball + 1.00 ; substitute this for "bat" in 1st equation
--------------------------------
ball+ (ball+1.00) = 1.10

ball+ ball = 1.10 - 1.00
2balls = 0.10
ball = 0.05 :)

I run into this a lot in my field (auto-racing) where people have a hard time translating real-life phenomenon into modeling equations. You have to be able to accurately model the existing reality first before you can play "what-if" test scenarios. :) We had one guy that claimed his car would do 280mph at Bonneville, but when asked to show his calculations on a stock car with stock HP, it came up with a ludicrous speed that was 25mph faster than what the real-life stock car can actually do... heh, heh..

How is this possible?

Even in this modern day, most people will read this and assume the doctor was male, even though it mentions nothing about the doctor being the father. If you exchanged to word "doctor" with "nurse," I think everyone would guess that it was the boy's mother.

Oh wait a minute...maybe the old man who fell was the biological father and the doctor adopted the boy? Or maybe it was like that show from the 1980's 'My Two Dads,' starring Paul Reiser, Greg Evigan and Staci Keanan :roflmao:
