Question

celeste wants to have her haircut and permed and also go to lunch. she knows she will need $86. the perm cost twice as much as her haircutand she needs $5 for lunch. how much does the perm cost

Answer 1

Answer:

Step-by-step explanation:

2x(the perm)+x(the haircut)+5(lunch)=50

2x+x+5=50

So the first thing we can do is subtract the 5 from both sides and add the x's

 

3x+5-5=50-5

3x=45 Now we can divide the whole problem by 3 to get:

x=15

Great, now we know how much the haircut cost! Just double that to find out how much the perm costs, $30. Let's check our answer:

$15(haircut)+$30 (perm)+$5(lunch)=$50 (total)
