Sarah has invested $7,800 in a savings certificate paying a guaranteed rate of 4.28% compounded quarterly for a term of eight years. Note this is a single payment. a. Find the interest rate per conversion interval. b. Find the future value of the investment at the end of eight years. . c. Find the total interest earned over the eight years. d. Set up the expression for finding the effective annual rate (EAR) of 4.28% compounded quarterly and evaluate the expression. Express your answer to four places after the decimal point. (Example: 0.1234)
1.
=4.28%/4=1.07%
2.
=7800*(1+4.28%/4)^(4*8)=10964.9613481915
3.
=7800*(1+4.28%/4)^(4*8)-7800=3164.96134819145
4.
EAR=(1+nominal rate/4)^4-1=(1+4.28%/4)^4-1=4.349185327996%
