Final answer:
Using the simple interest formula, on a principal of $1,000 with an annual interest rate of 5.5% for 2 years, the total interest earned is $110.
Step-by-step explanation:
To calculate the amount of simple interest earned on a principal of $1,000 at an annual interest rate of 5.5% over 2 years, you can use the formula:
Interest = Principal × rate × time
First, convert the interest rate from a percentage to a decimal by dividing by 100:
5.5% = 5.5 ÷ 100 = 0.055
Then, use the simple interest formula to find the interest:
Interest = $1,000 × 0.055 × 2
Interest = $110
The total interest earned after 2 years is $110.
