First find the future value of annuity ordinary
Fv=125.30×(((1+0.015÷12)^(12
×35)−1)÷(0.015÷12))
=69,156.05

Then find the monthly payment Use the formula of the present value of annuity ordinary
Pmt=69,156.05÷((1−(1
+0.015÷12)^(−12×20))
÷(0.015÷12))=333.71

After that Use the formula of the future value of annuity ordinary
fv=333.71×(((1+0.015÷12)^(12
×20)−1)÷(0.015÷12))
=93,333.60

Finally find the monthly payment using the formula of the future value of annuity due
Pmt=93,333.60÷1
+0.015÷12)^(12×20)−1)
÷(0.015÷12))×(1+0.015
÷12))=333.29answer

So the answer is c
