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

Respuesta :

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
