Step-by-step explanation:

This question deals with simple interest.

How much the balance is reduced in month one is the sum of the monthly payment and the interest paid in month one. So:

1484.9 + 937.5 = $2422.4

The beginning balance for month two is the starting amount ($225000) subtracted by two times the sum of the monthly payment and the interest paid in month one. So:

225000 - 2(1484.9 + 937.5)

= 225000 - 2(2422.4)

= 225000 - 4844.8

= $220155.2
