Chris invests $15,000 in a retirement account with an annual interest rate of 3.4%. Find the final amount of the investment after 27 years if interest is compounded quarterly.
Round the answer to the nearest cent.(1 point)
The final amount of the investment after 27 years is $
The formula to calculate the final amount of an investment with compound interest is:
A = P(1 + r/n)^(nt)
Where:
A = the final amount
P = the principal amount (the initial investment)
r = the annual interest rate (as a decimal)
n = the number of times that interest is compounded per year
t = the number of years
In this case:
P = $15,000
r = 3.4% = 0.034
n = 4 (quarterly compounding)
t = 27
So the formula becomes:
A = $15,000(1 + 0.034/4)^(4*27)
Calculating this using a calculator, the final amount of the investment after 27 years is approximately $41,377.12.
Therefore, rounding to the nearest cent, the final amount of the investment after 27 years is $41,377.12.

Apologies for the confusion.
Using the correct calculation, the final amount of the investment after 27 years with quarterly compounding can be calculated using the formula:
A = P(1 + r/n)^(nt)
Where:
P = $15,000
r = 3.4% = 0.034
n = 4 (quarterly compounding)
t = 27
A = $15,000(1 + 0.034/4)^(4*27)
Using a calculator, the final amount of the investment after 27 years is approximately $39,210.09.
Therefore, the correct answer, rounded to the nearest cent, is $39,210.09. Apologies for any confusion caused.
