Answer:
A = $41,250.00 total / 60 for monthly payment = $ 687.5
Step-by-step explanation:
(I = A - P = $8,250.00)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 33000(1 + (0.05 × 5)) = 41250
A = $41,250.00
The total amount accrued, principal plus interest, from simple interest on a principal of $33,000.00 at a rate of 5% per year for 5 years is $41,250.00.
