Answer: C. 6 hours


Step-by-step explanation:

Roy worked for 2 hours and earned $12.

First you want to know how much money he made in one hour. So you divide 12 by 2.

12 ÷ 2 = $6 per hour

Now you wanna know how many hours must he work at the same rate to earn $36.


$6 × 6hours = 36

So the answer is C. 6 hours
