Answer:
a. $198
b. 25 hours
Explanation:
a. You earn $11 per hour, and so if you work 18 hours, you multiply "11 x 18" to find out how much money you would make during that time period.
b. To find out how many hours you are required to work to be paid $275, you simply need to divide by 11, seeing as how that is how much you would be paid per hour. So, the equation would look like this: "275/11 = 25"
