Work Step by Step

RECALL: The future value $A$ of an investment/loan that is compounded continuously is given by the formula: $A=Pe^{rt}$ where $P$ = amount invested/borrowed $r$ = annual interest rate $t$ = time in years The given problem has: $P =\$1600 $ $r=9\%=0.09$ $t=5$ years Substitute the values into the given formula above to obtain: $A=\$1600(e^{0.09(5)}) \\A=\$2509.299497 \\A\approx \$2509.30$ Thus, the amount owed at the end of 5 years is $\$2509.30$.
