Question 1164640
formula to use is f = p * (1 + r) ^ n
f if the future value
p is the present value
r is the interest rate per time period (quarters of a year in this problem)
n is the number of time periods (quarters of a year in this problem)


your formula becomes f = 5,000,000 * (1 + .06/4) ^ (15 * 4)
solve for f to get f = 12,216,098.88
that's how much the investment will grow to during the investment period.
the interest earned will be that minus the initial investment = 12,216,098.88 minus 5,000,000 = 7,216,898.88.
