The amount accrued in a compound interest is given by the following formula:
A = P (1 + r/n) ^(nt)
Where:
A = This is the principal amount plus interests earned,
P = This is the loan amount or the money deposited.
r = the annual interest rate in decimal
n = the number of times that interest is compounded per year ( in this case it is twice a year - semiannually)
t = This is the total number of years the money is invested or borrowed
The following expression gives Nelson's payable amount after t years:
150,000(1.012)^2t
Compare the two expressions:
A = 150,000(1.012)^2t
A = P (1 + r/n) ^(nt)
From the expression, you can see that:
(1 + r/n) = 1.012
Therefore,
r/n = 1.012 - 1
r/n = 0.012
r = 0.012n
n = 2, since Nelson's interest, is compounded semiannually.
Therefore, r = 0.012 × 2 = 0.024
Since r is in decimal form, we convert this to %
0.012 × 100% = 2.4%
