Answer:
[tex]32x+21y[/tex]
Step-by-step explanation:
It's pretty much logic.
If [tex]x[/tex] individuals want a sweatshirt and each sweatshirt is $32, it would be [tex]32x[/tex].
If [tex]y[/tex] individuals want a sweatpant and each sweatpant is $21, it would be [tex]21x[/tex].
Add them together and BOOM! you got your answer: [tex]32x+21y[/tex]
I hope that helps! :)
