Final answer:
Ryan earns $562.50 in interest over 15 years.
Step-by-step explanation:
To calculate the amount of interest Ryan earns in 15 years, we can use the formula:
Interest = Principal × Rate × Time
Given that the principal amount (P) is $750, the interest rate (R) is 5%, and the time period (T) is 15 years, we can substitute these values into the formula:
Interest = $750 × 0.05 × 15
Simplifying the equation, we find that Ryan earns $562.50 in interest over 15 years.
