Henry invested $59,000 in an account paying an interest rate of 2% compounded quarterly. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 20 years?

To calculate the final amount in the account after 20 years with 2% interest compounded quarterly, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = the amount of money accumulated after n years, including interest
P = the principal amount (initial investment)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested for

Plugging in the given values:
P = $59,000
r = 2% = 0.02
n = 4 (quarterly compounding)
t = 20 years

A = $59,000(1 + 0.02/4)^(4*20)
A = $59,000(1 + 0.005)^80
A = $59,000(1.005)^80
A = $59,000(2.20804)
A = $130,099.36

Therefore, after 20 years, there would be approximately $130,099.36 in the account.
this is wrong
I apologize for the mistake. Let's recalculate the final amount in the account after 20 years using the correct formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = the amount of money accumulated after n years, including interest
P = the principal amount (initial investment)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested for

Given:
P = $59,000
r = 2% = 0.02
n = 4 (quarterly compounding)
t = 20 years

A = $59,000(1 + 0.02/4)^(4*20)
A = $59,000(1 + 0.005)^80
A = $59,000(1.005)^80
A = $59,000 * 2.191594
A = $129,302.45

Therefore, after 20 years, there would be approximately $129,302.45 in the account.
