Answer:
x + y ≤ 12
15x + 24y ≥ 240
Explanation:
The number of children is represented by x and the number of adults is represented by y.
We are given that:
1- The hairstylist can serve a maximum of 12. This means that the summation of x and y should not exceed 12. Therefore:
x + y ≤ 12
2- The cost per child (x) haircut is $15 and that the cost per adult (y) is $24.
We are also given that the hairstylist would like to earn a minimum of $240.
This means that the earnings could be more than $240. Therefore:
15x + 24y ≥ 240
Since we are not given any further information, therefore, the maximum number of inequalities that can be formed is two.
Hope this helps :)
