Answer:
$3,753.59
Explanation:
Value of debt at end of 5 years = $21,000 * (1 + 6%)^5
Value of debt at end of 5 years = $21,000 * 1.3382255776
Value of debt at end of 5 years = $28102.7371296
Value of debt at end of 5 years = $28,102.74
Let x be the annual payments:
x*[1 - (1 + 9%)^-13] / 9% = $28,102.74
x * [1-0.32617864688] / 0.09 = $28,102.74
x * 7.486904 = $28,102.74
x = $28,102.74 / 7.486904
x = 3753.58626
x = $3,753.59
