Answer

You need to deposit approximately \$3846.15 now to have \$5000 in 10 years with 3% simple interest.

Solution

Under simple interest, the future balance A after t years is given by the formula:   A = P(1 + rt) where:  P is the initial deposit (the principal),  r is the annual interest rate (in decimal form), and  t is the time in years. We are given:  A = $5000,  r = 3% = 0.03, and  t = 10 years. Plug these values into the formula:  5000 = P(1 + 0.03 × 10) Calculate 0.03 × 10:  0.03 × 10 = 0.30 Now, the equation becomes:  5000 = P(1 + 0.30) = P(1.3) Solve for P by dividing both sides by 1.3:  P = 5000 / 1.3 ≈ 3846.1538 Rounded to the nearest cent, the amount you need to deposit is approximately $3846.15.

To find out how much you need to deposit now to have $5000 in 10 years at a 3% simple interest rate, we use the formula for simple interest: \[ A = P(1 + rt) \] Where: - \( A \) is the amount of money accumulated after n years, including interest. - \( P \) is the principal amount (the initial deposit). - \( r \) is the rate of interest per year. - \( t \) is the time the money is invested for in years. Rearranging for \( P \), \[ P = \frac{A}{1 + rt} \] Substituting the known values: \[ P = \frac{5000}{1 + (0.03)(10)} = \frac{5000}{1 + 0.3} = \frac{5000}{1.3} \approx 3846.15 \] So, you would need to deposit approximately **$3846.15** now to reach $5000 in 10 years. In a twist of fate, simple interest is like a slow dance; the longer you keep it going, the more beautiful it becomes. Unlike compound interest, where your interest earns interest, in simple interest, it’s a straightforward journey—a guaranteed way to grow your money without any surprises. Just sit back, watch it grow and enjoy the slow simmer of your savings! Have you ever thought about how many fun places that money could take you once it matures? With that $5000 in 10 years, think of the options—perhaps a dreamy vacation, a slick new gadget, or even a small investment in something that excites you! Planning ahead and understanding your savings can open the door to new adventures. So keep on budgeting wisely and let that interest work its magic!
