    Answer: $78150 would be in the account after 8 years

    Step-by-step explanation:

    We would apply the formula for determining compound interest which is expressed as

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

    Where

    A = total amount in the account at the end of t years

    r represents the interest rate.

    n represents the periodic interval at which it was compounded.

    P represents the principal or initial amount deposited

    From the information given,

    P = $65,000

    r = 2.3% = 2.3/100 = 0.023

    n = 12 because it was compounded 12 times in a year.

    t = 8 years

    Therefore,.

    A = 65000 (1 + 0.023/12) ^12 * 18

    A = 65000 (1 + 0.00192) ^96

    A = 65000 (1.00192) ^96

    A = $78150
