Question

The owner of a hair salon charges $20 more per haircut than the assistant. Yesterday the assistant gave 12 haircuts. The owner gave 6 haircuts. The total earnings from the haircuts were $750. How much does the owner charge for a haircut? Solve by writing and solving a system of equations?

Answer 1

Let the owner's charge be $x
then the assistant's charge is x-20

6x + 12(x-20) = 750
6x + 12x - 240 = 750
18x = 990
x = 55

Answer 2

X: $55
