Ommmg please help me with this question I don’t understand it at all, I only have 2 minutes left for this test please help me I mean like I’m confused between surface area and area because they are both used for covering areas but like is it surface area or area and also explain why. Thanks.

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?
