Adolfo Ramirez purchased a microwave and dishwasher for $897. He made an 18 percent down payment and financed the remainder. What amount did he finance?

a. $791.01

b. $786.12C. $735.54

d. $766.34

This can be solve using the formula:

D = O (i) where D is the downpaymentO is the original prizei is the fraction of the downpayment

D = O (i) D = 897 (0.18) D = 897 (0.18) D = 161.46

so the amount he did finance is:F = 897 - 161.46F = $ 735.54 is the amount he finance
