Question

Horace is a professional hair stylist. Let CCC represent the number of child haircuts and AAA represent the number of adult haircuts that Horace can give within 777 hours. 0.75C+1.25A \leq 70.75C+1.25A≤70, point, 75, C, plus, 1, point, 25, A, is less than or equal to, 7 Horace gave 555 child haircuts. How many adult haircuts at most can he give with the remaining time? Choose 1 answer:

Answer 1

He can give almost 2 adult haircuts. This is correct on Khan Academy. Stay safe everyone.

Explanation:

Answer 2

At most 2 adult haircuts

Explanation:

The equation given is:

`0.75C+1.25A \leq 70`

This equation dictates the number of haircuts Horace gives in 7 hours.

Horace gave 5 child haircuts (C=5). So, that would make the equation:

`0.75C+1.25A \leq 7\\0.75(5)+1.25A \leq 7\\3.75+1.25A \leq 7\\1.25A \leq 7 - 3.75\\1.25A \leq 3.25\\A \leq (3.25)/(1.25)\\A \leq 2.6`

This means Horace can give LESS THAN or EQUAL to 2.6 haircuts.

2.6 haircuts doesn't make sense, so the maximum would be "2" haircuts.

Atmost 2 adult haircuts
