Grant and Kera are both 75 years old. When Kera was 20 she began investing $1000 a year into an RRSP paying an average of 6%/a compounded annually. Grant on the other hand, did not start to invest until age 50. He made an annual deposit of $3000 beginning at age 50. The average interest rate he received on his investment was 8%/a compounded annually. Solve each of the following using the TVM solver (graphing calculator finance application) I need help doing this even with formulas doesnt have to be with graphing calculator 1) What amount does each have today? For this question I dont know which formula I should be using or solving for in the calc Present Value or Future Value? 2)What should Grant have invested each year in order to have the same amount as Kera at age 75? I dont know what to do for this part, how would you use the calculator alone trial and error? 3.) If Grant could only afford to invest $3000 per month, what average rate of interest would result in his saving the same amount as Kera? I did this question and when i solved for interest i got a negative number y?
