A barber has 28 costomers and recives $64 in tips. The barber charges a flat rate for haircuts and makes a total of $456 including tips. How much money does the barber charge for each haircut

Answer 1

Cost of each haircut
`=\$14`

Let cost per customer haircut
`=\$x`

`Cost\ of\ 28\ customers=Cost\ of\ 1\ customer* total\ number\ of\ customers=28* x=28x\\\\Total\ cost=Cost\ of\ haircuts+Tips=28x+64\\\\`

He makes total
`$456`.

`28x+64=456\\28x=456-64\\28x=392\\x=(392)/(28)\\x=14`
