Andrew invests $9,000 at the end of each year for 20 years. the rate of interest andrew gets is 8% annually. using the tables found in the textbook, determine the final value of andrew's investment at the end of the twentieth year on this ordinary annuity. a. $88,362.90 b. $411,858.00 c. $88,632.90 d. $411,588.00

Given that Andrew invests $9,000 at the end of each year for 20 years. The rate of interest Andrew gets is 8% annually.

Now we need to determine the final value of Andrew's investment at the end of the twentieth year on this ordinary annuity.

So we can use annuity formula which is :

Where R=annual payment = 9000

i= rate of interest = 8% = 0.08

t= number of years = 20

S= future value

Now plug those values into above formula.

S=411857.678683

Hence final answer is approx $411858.
