Final answer:
To calculate the amount of principal and interest received, you can use the formula for compound interest. By plugging in the given values, the principal amount is approximately $342.55, and the interest received is approximately $132.45.
Step-by-step explanation:
To calculate the amount of interest received, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
- A is the future value of the investment, which is $475
- P is the principal amount that you want to find out
- r is the annual interest rate, which is 8.9% or 0.089
- n is the number of times the interest is compounded per year, which is 1 since it is compounded annually
- t is the number of years, which is 4
Now, we can plug in the values and solve for P:
$475 = P(1 + 0.089/1)^(1*4)
$475 = P(1 + 0.089)^4
$475 = P(1.089)^4
$475 = P(1.3856)
$475/1.3856 = P
P ≈ $342.55
Therefore, the amount of principal that you will receive is approximately $342.55 and the remaining amount of $475 - $342.55 = $132.45 will be the interest received.
