Answer:

Interest rate is 5.25% a year.

Step-by-step explanation:

r = (1/54)((22252.5/18000) - 1) = 0.004375

r = 0.004375

Convert decimal to percentage

R = 0.004375 * 100 = 0.4375%/month

Calculate annual rate

0.4375%/month × 12 months/year = 5.25% per year.

The interest rate is 5.25 percent. I got this by doing 4252/81000 (18000x4.5) and got 0.0525 and then multiplied by 100 (decimal to percent)
