Hi, can anyone show me how to do this problem? 100 points for this. in advance

Combine the information in the problem and the chart using the average balance method to solve the problem.

You just purchased two coins at a price of $670 each. because one of the coins is more collectible, you believe that its value will increase at a rate of 7.1 percent per year, while you believe the second coin will only increase at 6.5 percent per year. if you are correct, how much more will the first coin be worth in 15 years?
