Final answer:
To calculate the future amount with simple interest, use the formula: Total Future Amount = Principal + (Principal * Rate * Time). In this case, Eric will have $740 in 15 years.
Step-by-step explanation:
To calculate the future amount with simple interest, we can use the formula:
Total Future Amount = Principal + (Principal * Rate * Time)
In this case, the principal is $500, the rate is 8.00%, and the time is 15 years. Plugging these values into the formula, we get:
Total Future Amount = $500 + ($500 * 0.08 * 15) = $740
Therefore, Eric will have $740 in 15 years.
