Answer:
Step-by-step explanation:
$17 x 40 hours = $680 which means that this is the max amount of money Denise can earn without going over 40 hours.
$850 - $680 = $170 Which is the amount she made by working overtime last week.
$170/$17 = 10 hours that she has worked overtime last week (we divide 170 by 17 since 17 is how much she makes per hour and 170 is the amount of money she made overtime).
