Thank you so much in advance for your support. So I receive this exercise in one of my classes and my answers are not matching/are not the right ones. Would appreciate if someone can help me with it.

You want to buy a land under the following conditions: $8,800 of initial installment (premium) and the balance through 36 equal quarterly payments for $1,384, the first payment in exactly two years. Find the cash value if the seller charges an interest rate of 20% capitalizable quarterly.
