Explanation:
a. What was the amount of interest paid by Debbie?
Interest is calculated as:
= PRT
= (16500 × 9% × 1)
= 16500 × 0.09 × 1
= $1485
Debbie paid $1485 as interest.
b. What was the interest rate paid by Jan?
Interest = PRT/100
6450 = (107500 × R × 1) / 100
6450 × 100 = 107500R
645000 = 107500R
R = 645000 / 107500
R = 6.0
The interest rate is 6.0%
