Investing When the interest on an investment is compounded continuously, the investment grows at a rate that is proportional to the amount in the account. If $20,000 is invested (when t = 0) and the amount in the account after 22 years is $280,264, find the function that gives the value of the investment as a function of t . What is the interest rate on this investment?
