Cassandra is calculating how much interest she will earn on investments that are earning simple interest. she knows that simple interest is paid only on the original amount that was deposited (principal). for one amount of money that was invested for three years, she wrote the equation:
i=500(.025)(3) = 37.50


a.in cassandra's equation, identify the principal, interest, rate, and time


b. use this formula to identify how much interest you would earn if you deposit $200 for 5 years at an annual (yearly) simple interest rate of 4%




thanks!
