An investment with an initial deposit of $2,263 is growing at an interest rate of 6.31% compounded semi-annually. Round all answers to two decimal places if necessary. 1. Find the accumulated amount of the investment at the end of 2 years. PNY = C/Y = N = I/Y = % PV = $ PMT = $ FV = $ 2. The interest rate changes to 8.13% compounded quarterly after the first 2 years. Calculate the accumulated amount in this investment at the end of 8 years. P/Y = CNY = N = IY = % PV = $ PMT = $ FV = $ 3. Find the total amount of interest accumulated during the entire 8 years of the investment. Total Interest = $ (enter a positive value)
