Answer:
2 3/4z +3/10
Step-by-step explanation:
3/4(z+ 2/5)+2z
Distribute the 3/4
3/4z + 3/4*2/5 +2z
3/4z + 6/20 +2z
3/4z +3/10 +2z
Combine like terms
2 3/4z +3/10
I assume you would like to know the cost of her perm and haircut, so thats what I will answer.
She needs $5 for lunch, and er perm will cost twice as much as her haircut. We have $45 left, so we can divide it by three (because the perm will cost twice as much as the haircut, as this why we can figure out how much that is) 45÷3 is 15.
So now we know her haircut will cost $15 and her perm will cost $30.
