Final Answer :
B
Explanation :
To find the amount in the account when Jackson is 40, we use the formula for continuous compounding interest, A=PertA = Pe^{rt}A=Pert , where AAA is the amount of money accumulated after n years, including interest, PPP is the principal amount (the initial amount of money), rrr is the annual interest rate (decimal), and ttt is the time the money is deposited for in years. Here, P = $5,000 , r=3.8%=0.038r = 3.8\% = 0.038r=3.8%=0.038 , and t=40−18=22t = 40 - 18 = 22t=40−18=22 years. Plugging these values into the formula gives us A=5000e0.038×22A = 5000e^{0.038 \times 22}A=5000e0.038×22 , which calculates to approximately $11,535.60.
