Answer

You need to deposit approximately \$3,703.88 now to have \$5,000 in 10 years with a 3% annual interest rate compounded monthly.

Solution

To determine the amount you need to deposit now (the present value, PV) so that you have \$5000 in 10 years with an interest rate of 3% compounded monthly, you can use the formula for the present value of a future sum:   PV = FV / (1 + i)^n where: • FV is the future value (\$5000), • i is the periodic interest rate, and • n is the total number of compounding periods. Step 1: Calculate the periodic rate. Since the annual interest rate is 3% and interest is compounded monthly:   i = 0.03 / 12 = 0.0025 Step 2: Calculate the number of periods. Since there are 12 months in a year and the total time is 10 years:   n = 10 × 12 = 120 Step 3: Substitute into the formula.   PV = 5000 / (1 + 0.0025)^120   PV = 5000 / (1.0025)^120 Step 4: Compute (1.0025)^120. Using a calculator:   (1.0025)^120 ≈ 1.3498588 Step 5: Compute PV.   PV ≈ 5000 / 1.3498588 ≈ 3703.88 Rounded to the nearest cent, you need to deposit approximately \$3,703.88.

To find out how much you would need to deposit now to have \( \$5000 \) in 10 years with an interest rate of \( 3\% \) compounded monthly, we can use the formula for compound interest: \[ P = \frac{A}{(1 + \frac{r}{n})^{nt}} \] Where: - \( P \) is the present value (the deposit now), - \( A \) is the amount of money accumulated after n years, including interest, - \( r \) is the annual interest rate (decimal), - \( n \) is the number of times that interest is compounded per year, and - \( t \) is the number of years the money is invested or borrowed. In your case: - \( A = 5000 \) - \( r = 0.03 \) - \( n = 12 \) (monthly), - \( t = 10 \). Plugging in the numbers: \[ P = \frac{5000}{(1 + \frac{0.03}{12})^{12 \times 10}} \] Calculating: \[ P = \frac{5000}{(1 + 0.0025)^{120}} = \frac{5000}{(1.0025)^{120}} \approx \frac{5000}{1.349353} \approx 3706.44 \] So, you would need to deposit approximately **$3706.44** now to have **$5000** in your account in **10 years** at a **3%** interest rate compounded monthly.
