Final answer:
The interest earned on a $8,000 deposit in a savings account with a 4.5% interest rate over five years is $1,800.
Step-by-step explanation:
To calculate the interest earned on a savings account, we can use the formula:
Interest = Principal × Rate × Time.
In this case, the principal is $8,000, the rate is 4.5%, and the time is 5 years.
Substituting these values into the formula, we get: Interest = $8,000 × 0.045 × 5 = $1,800. Therefore, the correct answer is C. $1,800.
