Final answer:
To find the percentage of income refunded, divide the amount returned by the annual income and multiply by 100. In this case, Mick had 6% of his income returned to him.
Step-by-step explanation:
To calculate the percentage of Mick's income that he had returned to him, we need to divide the amount of taxes returned ($2,700) by his annual income ($45,000) and then multiply by 100. This can be done using the following formula:
Percentage Returned = (Returned Taxes / Annual Income) × 100%
Plugging in the values, we get:
(2700 / 45000) × 100% = 0.06 × 100% = 6%
Therefore, Mick had 6% of his income returned to him.
