Tools like a calculator and/or very simple Excel spreadsheet would work.


The things is, actually going shopping for food every day for a week could be a very eye-opening exercise. The OP, and others who are wondering the same thing, might discover things like that traditional rolled oats run about $1.06 / 750 grams ... but Kelloggs Fruit Loops are about $8.34 / 500 grams*.

Get the traditional rolled oats, make them for breakfast for a week ... and see how they work for you. Will you be able to cook them on a tour? Would you prefer to get something you don't have to cook? Go for a ride after breakfast and see how you feel. Many people find that the rolled oats provide lots of energy (they work well for Rowan) ... but a few of us feel ravenously hungry, and a bit weak and shaky, about an hour after we eat them. You won't know until you try. How much you want to cook up for breakfast may vary too ... your 750 gram bag might last a few days or a week or more. Again, you won't know until you try.
