Answer:
a. $55,390.29
b. $61,412.20
Step-by-step explanation:
a. To find the present value of your windfall, each value must be brought back to the present year at a rate of 3.5% per year. The present value is:
[tex]PV = \frac{10,000}{1.035}+\frac{20,000}{1.035^2}+\frac{30,000}{1.035^3}\\PV = \$55,390.29[/tex]
The present value of your windfall is $55,390.29.
b. To find the future value of your windfall at the date of the last payment, simply compound the preset value amount obtained on the previous item for three years at a rate of 3.5%:
[tex]FV =55,390.29*(1.035)^3\\FV=\$61,412.20[/tex]
The future value of your windfall is $61,412.20.
