Ugh. You should not have bought a K-mart bike to begin with.
A new set of wheels plus a chain will cost more than 77$ if you add the work. If you do it yourself, you'll need to buy specialized tools.
Go to a local bike shop and ask if they could do the repair and for how much. They might refuse because you bought a piece of junk from the supermarkert. Or ask K-mart about repairs.
Do not invest in another piece of junk.
Support your local shops and buy a real bike, which will last (not need new wheels after a couple hundred miles. The chain is something that does need to be replaced after a certain amount of use).
