Answer:
Molly earned $55.44 in interest at the end of six years.
Explanation:
To calculate the interest earned by Molly's savings account, we can use the formula:
Interest = Principal x Rate x Time
where:
Principal is the initial amount of money deposited ($220.00)
Rate is the annual interest rate (4.2% or 0.042 as a decimal)
Time is the number of years the money is invested (6 years)
Plugging in the values, we get:
Interest = $220.00 x 0.042 x 6
Interest = $55.44
Therefore, Molly earned $55.44 in interest at the end of six years.
