Answer:
Melody have now $27.75
Step-by-step explanation:
We will proceed to solve the problem in parts so that it can be better understand
so
1) Originally Melody had $45
2) She spent $32.75 on a blouse
so
In this moment Melody has --------> $45-$32.75=$12.25
3) Her mother gave her $15.50
so
In this moment Melody has --------> $12.25+$15.50=$27.75
therefore
Melody have now $27.75
Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
