Question

Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need 86$. The perm cost twice as mucho as her haircut and she need 5 for lunch

Answer 1

Perm = 2 times haircut so perm = 2h Haircut + perm + lunch = 86 (writing out in words can sometimes help) 2h + h + 5 = 86 (replace with letters) 3h + 5 = 86 (simplify) 3h = 81 (subtract 5 from each side) h = 27 (divide both sides by 3) A haircut costs $27, so a perm costs $54
