Tom invested $7,000 at 6.5% interest compounded monthly. How much will be in this account after 18 months?

To find the amount in the account after 18 months, we can use the formula for compound interest:

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

Where:
A is the amount after time t
P is the principal amount (the initial investment)
r is the annual interest rate (in decimal form)
n is the number of times that interest is compounded per year
t is the time in years

Given:
P = $7,000
r = 6.5% = 0.065 (decimal form)
n = 12 (compounded monthly)
t = 18 months = 18/12 = 1.5 years

Now, let's plug the values into the formula:

A = 7000(1 + 0.065/12)^(12*1.5)

Calculating this expression will give us the amount in the account after 18 months.
