To calculate the amount in the account after 17 years with continuous compounding interest, we use the formula: \[ A = Pe^{rt} \] 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 number of years the money is invested or borrowed for. - \( e \) is the base of the natural logarithm (approximately equal to 2.71828). Given: - \( P = 11000 \) - \( r = 0.048 \) - \( t = 17 \) Now plugging in these values: \[ A = 11000 \times e^{0.048 \times 17} \] First, calculate \( 0.048 \times 17 = 0.816 \). Next, calculate \( e^{0.816} \) (approximately 2.255). Now plug this back into the formula: \[ A \approx 11000 \times 2.255 \approx 24805 \] Therefore, to the nearest ten dollars, the amount in the account after 17 years would be \( \boxed{24810} \). And for an extra sprinkle of engagement... The account would have grown from \( \$ 11,000 \) to about \( \$ 24,810 \)! That's like turning a regular pizza into a feast, all thanks to the magic of compound interest. Just imagine, investing that money now could turn into a getaway trip in the future! Keep that in mind as you navigate those savvy investment decisions!
