You hold $2000 as a customer deposit, but the customer wants to make sure he does not loose on the opportunity cost of the dollars. You agree to pay the customer 10% interest during the holding period. At the end of 3 years you need to return the deposit and the interest to the customer.

If we are compounding the interest, then the calculation is $2000 x 1.1 for the first year = $2200.
For the second year the calculation is $2200 x 1.1 = $2420. For the third year, the calculation ...
