An initial amount of $1700 is invested in an account at an interest rate of 4% per year, compounded continuously. Assuming that no withdrawals are made, find the amount in the account after seven years
Do not round any intermediate computations, and round your answer to the nearest cent.

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?
