Answer:
$1476.71
Explanation:
Formula = pmt(((1+r)^n)-1)/I
I = nominal interest rate
Pmt = dollar amount
r = interest rate
N = number of period
4930 = pmt(((1 +0.109)^3)-1)/0.109
4930 = pmt(1.109^3)-1/0.109
4930 = pmt(1.3639-1)/0.109
4930 = pmt(0.3638/0.109)
4930 = pmt3.3385
Pmt = 4930/3 3385
= $1476.71
