Ashley Rowe · Answer 1

Depends on the missing variable.

Step-by-step explanation:

His tips are based on his food sales. He would need to sell $21.66 each hour he worked to make $3.90 (3.90/.18) for it to be proportional.

Zoey Whitaker · Answer 2

He earns 18% tips on his food sales. So, his tips are proportional to the amount of food he sells.

From what you know about the restaurant business, what would have to be true for his tips to be proportional to the amount of hours he works?

Do you think that situation (Michael's amount of food sales being the same every hour) is likely in a real restaurant?
