Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need $95. The perm costs twice as much as her haircut and she needs $5 for lunch. How much does the perm cost?

She needs 95$ if you subtrack the 5 from the 95$ that gives you 90$. You subtract that 5$ from the 95$ because it was 5$ for lunch and you need to double the 90$ for her hair perm which is 180. Your answer is 180

So perm cost 2 times as hair cut

perm=2 times haircut

she also needs 5 dollars for lunch

so therefor if 95 is enough to cover it we do

cost=lunch+perm+haircut

cost=5+perm+haircut

subsitute

95=5+2 times haircut+1 time haircut

add like terms

95=5 + 3 times haircut

subtract 5 from both sides

90=3 times haircut

diide by 3

30=haircut

subsitute

perm=2 times haircut=2 times 30=60

perm=$60
