Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need $68. The perm costs twice as much as her haircut and she needs $5 for lunch. How much does the perm cost?
total is 68 and the perm is 2 times as much as her haircut and her lunch is $5 so... 2h+h+5= 68 (add like terms) 3h+5 = 68 (subtract 5 from both sides) -5 - 5 3h = 63 (divide by 3) h= 21 so if her haircut is 21 dollars 21*2= $42 her perm cost 42 dollars
