That's a pretty open-ended question but Murray made a lot of pretty low-end, inexpensive bikes. It's maybe a late 1980's? model which seem to be selling for $25+ dollars depending on your area and the seller and buyer. Good thing is that a cheap bike from that era is going to be a little more durable than one of the current Big Box Store bikes. It looks in pretty good shape so maybe doesn't need any new parts, but most parts can be replaced with current similar parts if needed. Your brakes are probably not that great at stopping but with some better pads for around $15+ you can improve them a bit. Not much more to say about it than that. If you enjoy riding it then be happy and maintain it properly and it should serve you well.
