Final answer:
Mrs. Lockwood will earn $737.25 in simple interest after 6 years.
Step-by-step explanation:
To calculate the simple interest earned, we can use the formula:
Simple Interest = Principal (P) * Rate (R) * Time (T)
Given that Mrs. Lockwood invests $2,900 at a rate of 4.25% per year for 6 years, we can plug in these values into the formula:
- P = $2,900
- R = 4.25% = 0.0425 (convert percentage to decimal)
- T = 6
Using the formula, we can calculate the simple interest:
Simple Interest = $2,900 * 0.0425 * 6 = $737.25
Therefore, Mrs. Lockwood will earn $737.25 in simple interest after 6 years.
