Final answer:
The annual interest rate is 3.5%.
Step-by-step explanation:
To find the annual interest rate, we can use the formula for simple interest:
Interest = Principal x Rate x Time
Given that the principal is $6,000, the interest is $1,050, and the time is 5 years, we can rearrange the formula to solve for the rate:
Rate = Interest / (Principal x Time)
Substituting in the given values: Rate = $1,050 / ($6,000 x 5) = $1,050 / $30,000 = 0.035 = 3.5%
Therefore, the annual interest rate is 3.5%.
