Rory Riley is interested in buying a computer. At Radio Shack, she picks out a computer and a printer for a total cash price of $2,550. The salesperson informs her that if she qualifies for an instalment loan, she may pay 10% down and finance the purchase with payments of $125 monthly for two years. What is the finance charge for this loan? What is the deferred purchase price? What is the annual percentage rate charged?
