Answer:
5.784%
Explanation:
PV = $91000
PMT = -$1750
N = 60
FV = $0
Using the financial calculator to solve for I/Y
Interest yield = CPT I/Y(91000, -1750, 60, 0)
Interest yield = 0.00482
Interest yield = 0.482%
Highest rate APR = 0.482%*12
Highest rate APR = 5.784%
So, assuming monthly compounding, the highest rate i can afford on a 60-month APR loan is 5.784%.
