Explanation / Answer

The effective annual rate is 9.5%.
Let the effective monthly rate be i%.

Thus.
(1 + i)12 = (1 + 9.5%)
On solving we get i = 0.7592%

Let the monthly payment be M.

Value of Loan = P.V. of future payments
90000 = M*PVA(0.7592%,30*12)
90000 = M*123.0650
M = 731.32

THUS, MONTHLY PAYMENT IS OF $732.
