You buy a car for $$34,800$ and finance it with an installment loan with payments for $60$ months. The loan at $7\%$ APR would require monthly payments of $$612\mathrm{.}38.$ The same loan at $6\%$ APR would require monthly payments of $$603\mathrm{.}19.$ How much would you pay in interest for the $6\%$ APR? How much would you pay in interest for the $7\%$ APR?

How much more interest would you pay at $7\%$ rather than $6\%$ over the life of the loan?
