# 1
The total interest added on is 42400*0.024*5 = 5088 dollars

So the total amount to pay back is 42400 + 5088 = 47488

Divide this among 60 months (note: 5 yrs = 12*5 = 60 months) to get

47488/60 = 791.47

So the monthly payment is 791.47 dollars.
=======================================================
# 2
A = P(1 + r/n)^(nt)

A = 3940(1 + 0.095/12)^(12*10)

A = 10149.66

So your answer was very close, you just forgot the 66 cents.
