Tamara opens an account with an investment firm with a principal deposit of $500. The firm offers interest at an annual rate of 3.5% compounded monthly. Which expression below could be used to model the value of Tamara's account, A, after t years of accruing interest?

Richard made an investment of $500,000. Four years later, the value of the investment had doubled in value. If the interest rate is compounded annually, what is the approximate annual interest rate?

^{Round your answer to the nearest tenth of a percent.}

Write the equation of an exponential function in the form of y=a(b)^x with the following characteristics:

Initial Value: 500

Growth rate: 15%
