Suppose that P dollars in principal is invested in an account earning 2.1 % interest compounded continuously. At the end of 2 yr, the amount in the account has earned $193 .03 in interest. a. Find the original principal. Round to the nearest dollar. b. Using the original principal from part (a) and the model A = P e r t , determine the time required for the investment to reach $6000 . Round to the nearest year.
