Problem of the Month

When Marta was born, her grandparents started a college savings fund for her by investing $15,000 in a savings account that compounds continuously. When Marta finished eighth grade at age thirteen, the account held $71,382.32.

How much will the account hold when Marta graduates at age eighteen? What will the account's instantaneous rate of change be then?

Provide your answer on a standard sheet of paper. Please make sure you have your first name, last name, and ID number written on the top of your paper. Provide your answer highlighted or boxed, then provide your solution (how did you solve it) below that. Turn the paper in to the Turn-in envelope (on the bulletin board next to Ms. Celaya's classroom).
