Answer: $7,716.76
Explanation:
Ian's friend will have to pay a specific annual payment per year so this is an annuity.
The $25,000 is the present value of the payments.
25,000 = Annuity * Present Value interest factor of Annuity, 9%, 4 years
25,000 = Annuity * 3.2397
Annuity = 25,000/3.2397
= $7,716.76
