Please explain how to solve this equation with substitution: 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 haircuts were $750. How much does the owner charge for the haircut? Solve by writing and solving a system of equations.

  • Math -

    o=A+21
    6o+12A=750

    put the first equation into the second.
    6(A+21)=12A=750
    now simplify, solve for A.
    Then, O=A+21
