Answer:

$275.6

Explanation:

Compound interest:

The compound interest formula is given by:


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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

In this question:


P = 4000, r = 0.08, t = 12

Anually:


n = 1

Then


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


A(12) = 4000(1 + (0.08)/(1))^(12)


A(12) = 10072.68

Quarterly:


n = 4

Then


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


A(12) = 4000(1 + (0.08)/(2))^(12*4)


A(12) = 10348.28

How much would the future value of the investment increase?

10348.28 - 10072.68 = 275.6

The future value of the investment would increase by $275.6.
