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?
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
