2. Suppose you invest $1200 at the end of each year into an account that pays an annual interest rate of 8% compounded quarterly. How much is in the account after 10 years?

3. Consider the account from Problem #2.

How much would I have to pay into the account to accumulate $100,000 after 10 years? Round your answer to the nearest cent. (Remember that the account pays an annual interest rate of 8% compounded quarterly.)
