Answer: n=0
Step-by-step explanation:
The monthly payment for loans with no fees is expressed by a formula. The monthly payment equation is expressed as:
P = (P° x r x (1+r)^N) / ((1+r)^N -1)
<span>where P is the monthly payment, P° is the loan amount, r is the APR, N is the number of monthly payments
We substitute the values and manipulate where one side contains the unknown term r.
</span><span>27.50/835 = ( r x (1+r)^36) / ((1+r)^36 -1)
</span>
Using some functions in the calculator we obtain,
r = 9.51 x 10^-3
Thus, the problem above has an APR of 0.95% monthly.
