Answer

You should invest approximately \$3,073.35 now.

Solution

We use the formula for continuous compounding, which states that   A = P · e^(rt), where  A = the future amount,  P = the present investment,  r = the annual interest rate (in decimal),  t = the time in years. We want A = 3500 dollars, r = 0.065, and t = 2 years. Rearranging the formula to solve for P gives:   P = A / e^(rt). Substitute the known values:   P = 3500 / e^(0.065 × 2)     = 3500 / e^(0.13). Now, compute e^(0.13):   e^(0.13) ≈ 1.13883 Thus,   P ≈ 3500 / 1.13883     ≈ 3073.35. So, you should invest approximately $3,073.35 now.

Bonus Knowledge

To find the amount that should be invested now, we can use the formula for continuous compounding, which is given by: \[ P = A \cdot e^{-rt} \] where: - \( P \) is the present value (the amount to be invested now), - \( A \) is the amount of money desired in the future (\$3500), - \( r \) is the interest rate (6.5% or 0.065), - \( t \) is the time in years (2 years), - \( e \) is the base of the natural logarithm (approximately equal to 2.71828). Plugging in the values: \[ P = 3500 \cdot e^{-0.065 \cdot 2} \] Calculating \( -0.065 \cdot 2 \): \[ -0.065 \cdot 2 = -0.13 \] Now, calculating \( e^{-0.13} \): \[ e^{-0.13} \approx 0.876 \] Thus, \[ P \approx 3500 \cdot 0.876 = 3066 \] Finally, rounding to the nearest cent, the amount to be invested now is approximately: \[ \boxed{3066.53} \]
