King wants to have her hair cut and permed and also go to lunch. she knows she will need $77. the perm costs twice as much as her haircut and she needs $5 for lunch how much does the perm cost?

Cost of haircut = xCost of perm = 2x  equation in words: haircut + perm + lunch = 77 2x +x + 5 = 773x + 5 = 773x = 72x= 24 since x represents the cost of the haircut, the haircut is $24. The perm costs $48. i hope this helps!
