Final answer:
To calculate the amount deducted for taxes, multiply the earnings by the tax rate. In this case, $28.80 was deducted for taxes.
Step-by-step explanation:
To find out how much was deducted for taxes, we can use the formula:
Deduction amount = earnings * tax rate
Plugging in the values from the question:
Earnings = 40 hours * $9 = $360
Tax rate = 8% = 0.08
Now we can calculate the deduction amount:
Deduction amount = $360 * 0.08 = $28.80
Therefore, $28.80 was deducted for taxes.
