Question 1169273
the equation to use for this is f = p * (1 + r) ^ n
f is the future value
p is the present value
r is the interest rate per time period.
n is the number of time periods.


your time periods are in years.


when p = 12000 and r = 5% per year / 100 = .05 per year and n = 2028 - 2019 = 9 years, then the equation becomes:


f = 12000 *  (1 + .05) ^ 9 = 18615.93859


round to the nearest penny = 18615.94


the interest earned is 6615.93859.


round to the nearest penny = 6615.94.


that becomes the present value and n becomes 5 and r stays at .05 per year.
the formula becomes:


f = 6615.93859 * (1 + .05) ^ 5 = 8443.800443.


round to the nearest penny to get 8443.80.


that's the interest after 5 years.


the additional interest earned is 8443.800443 minus 6615.93859 = 1827.861852.


round to the nearest penny to get additional interest earned = 1827.86.


your questions was how much will the interest earn after 5 years.


i believe the answer to that would be 1827.86.


a summary of what happened.


12000 grew to 18615.94 in 9 years.
interest earned was 18615.94 - 12000 = 6615.94
6615.94 grew to 8443.80 in 5 years.
interest earned was 8443.80 - 6615.94 = 1827.86
