I do not think that this problem is for simple interest.
As this problem is worded, it is a typical loan problem and should be solved as a loan problem
by different way comparing with the post by the other tutor.
Use the standard formula for the monthly payment for a loan
M =
where P is the loan amount; r = is the effective interest rate per month;
n is the number of payments (same as the number of months); M is the monthly payment.
In this problem P = $75000; r = ; n = 2*12+8 = 32 is the number of monthly payments.
Substitute these values into the formula and get the monthly payment
M = = $2679.82 (rounded).
Thus, the monthly payment is $2679.82 (the monthly installment)
The total amount of money expected to be paid is 32 times this monthly installment
32 * 2679.82 = 85,754.24 dollars.
The difference $85,754.24 - $75,000 = $10754.24 is the interest John pays to the Hire Purchase Company.
ANSWER. The total amount of money expected to be paid to the Hire Purchase Company is 85,754.24 dollars.
Solved.
