Answer: 4 years
Explanation:
First find the amount Rula borrowed from her hometown bank:
= Price of car - Down payment
= 15,000 - 2,000
= $13,000
The amount that Rula is to pay is an annuity. The loan is the present value of that annuity.
Present value of annuity = Annuity * Present value interest factor of annuity
13,000 = 4,280 * Present value interest factor of annuity
Present value interest factor of annuity = 13,000 / 4,280
= 3.0373
Use an annuity table to find out the year that 12% as a discount rate intersects with, such that the present value of interest factor of annuity is 3.0373.
That number is:
= 4 years
