Final answer:
The coin machine will give Ashley back $4.4945.
Step-by-step explanation:
To find out how much money the machine will give Ashley back, we need to calculate 8.9% of the total amount she inserted. Since the ratio is maintained even when a fraction of a dollar is inserted, we can calculate this directly. We need to find 8.9% of $50.50, which is:
8.9/100 × 50.50 = $4.4945
Therefore, the machine will give Ashley back $4.4945.
