Final answer:
To calculate the interest earned, we can use the formula: Interest = Principal × Rate × Time. Plugging in the values, Fred will have earned approximately $14,700.87 in interest after 27 years.
Step-by-step explanation:
To calculate the interest earned, we can use the formula:
Interest = Principal × Rate × Time
Where:
- Principal = $11,681
- Rate = 4.71% = 0.0471 (expressed as a decimal)
- Time = 27 years
Plugging in the values, we have:
Interest = $11,681 × 0.0471 × 27
Calculating this, we find that Fred will have earned approximately $14,700.87 in interest after 27 years.
