Answer: Mary makes $374 for 17 hours of work.
Explanation:
Begin by getting the hourly pay. Do this by dividing the amount they made by how many hours they worked:
$176 / 8 hours = $22 / hour
Now you know the hourly rate, multiply it by how many hours she would've worked:
$22 * 17 hours = $374 for 17 hours of work.
