A man borrowed $18,000 to buy a car. If he pays a four and a half percent interest rate, what will the car cost in 3 years? (length of loan)

Respuesta :

Simple interest:
Final value = principle (starting balance) x interest x time in years
Fv = PiN

18,000 x 0.045 x 3 = $2430
2430 + 18000 = $20430
