If a hairstylist makes $66 a day and a $13 tip for each hair cut, how many haircuts does he need to do to make $170 in one day?

Question

A hairstylist makes $66 each day that he works and makes approximately $13 in tips for each hair cut he gives. If he wants to make $170 in one day, at least how many haircuts does he need to give?

Answer 1

Hello Sarah,

Let H be the number of haircuts in one day.  Then the inequality would look like:

66 + 13H ≥ 170,

 

→ 13H ≥ 104 (by subtracting 66 from both sides)

→ H ≥ 8 (by dividing both sides by 13).

 

So, the hairstylist has to do at least 8 haircuts in one day to make at least $170.

 

I hope the above helps, and thank you for posting the question.
