Math Problem Statement

The present value of FV dollars compounded at an interest rate i per period for n periods is PV=FV/(1+i)^n. In the formula, PV represents the present value, FV is the future value after n compounding periods. When the annual interest i is compounded m times per year, the interest rate per period is understood to be i/m. Find the present value of the given future amount of $10,752.34 at 3.3% compounded annually for 5 years.​(Do not round until the final answer. Then round to the nearest cent as​ needed.)

Solution

To solve this problem, we will use the present value formula:

PV=FV(1+i)nPV = \frac{FV}{(1 + i)^n}

where:

  • FV=10,752.34FV = 10,752.34 (the future value),
  • i=0.033i = 0.033 (3.3% annual interest rate),
  • n=5n = 5 years (since it's compounded annually, nn is 5).

Now, let's plug in the values into the formula:

PV=10,752.34(1+0.033)5PV = \frac{10,752.34}{(1 + 0.033)^5}

Step-by-step calculation:

  1. Calculate 1+0.033=1.0331 + 0.033 = 1.033.
  2. Raise 1.033 to the power of 5:

1.0335=1.1752761.033^5 = 1.175276

  1. Divide the future value by this result:

PV=10,752.341.1752769149.41PV = \frac{10,752.34}{1.175276} \approx 9149.41

So, the present value is approximately $9,149.41.
