This question is about compound interest. The formula for compound interest is A = P(1 + r/n)^(nt), 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 (in decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years. In this case, we are looking for the principal amount P, so we rearrange the formula to P = A / (1 + r/n)^(nt). Given that A = $50,000, r = 8% or 0.08, n = 1 (since it's compounded annually), and t = 5 years, we substitute these values into the formula to find P.
