Answer:

The nominal annual interest rate is 15%.

The effective interest rate is 16.08%.

Step-by-step explanation:

$9,375 = $325 (P/A, i%, 36)(P/A, i%, 36)

= $9,375/$325= 28.846

From compound interest tables, i = 1.25%

Nominal Interest Rate= 1.25 x 12= 15%

Effective rate = (1+ (0.15/36))^36-1=1.004^36-1= 16.08%
