To find the amount to invest now, you can use the formula for continuous compounding: \[ A = Pe^{rt} \] Where: - \( A \) is the amount of money accumulated after n years, including interest. - \( P \) is the principal amount (the initial amount of money). - \( r \) is the annual interest rate (decimal). - \( t \) is the time in years. - \( e \) is Euler's number (approximately 2.71828). You need \( A = 3500 \), \( r = 0.05 \), and \( t = 7 \): Rearranging the formula to solve for \( P \): \[ P = \frac{A}{e^{rt}} \] Now plug in the numbers: \[ P = \frac{3500}{e^{0.05 \times 7}} = \frac{3500}{e^{0.35}} \] Calculating \( e^{0.35} \) gives approximately \( 1.419067 \): \[ P = \frac{3500}{1.419067} \approx 2467.25 \] Thus, you should invest approximately **$2467.25** now to have $3500 in seven years.
