Answer:
The answers are:
A) total interest = p x r x t
where:
- p = $9,200
- r = 10%
- t = 2 years
total interest = $9,200 x 10% x 2 = $1,840
B) the total cost of the car = down payment + principal + total interest
total cost = $2,300 + $9,200 + $1,840 = $13,340
C) monthly payment = (principal + total interest) / total number of payments
monthly payment = ($9,200 + $1,840) / (12 x 2) = $11,040 / 24 = $460
D) APR = (total payments x total interest) / [principal x (total payments +1)]
APR = (24 x $1,840) / ($9,200 x 25) = 0.192 or 19.2%
