Answer:
The maximum number of volleyballs that she can buy is 19
Step-by-step explanation:
Let
x ----> the number of volleyballs
we know that
The cost of each volleyball net ($28) by the number of volleyball nets (4) plus the cost of each volleyball ($7) multiplied by the number of volleyballs (x) must be less than or equal to $250
so
The inequality that represent this situation is
[tex]28(4)+7x\leq 250[/tex]
Solve for x
[tex]112+7x\leq 250[/tex]
subtract 112 both sides
[tex]7x\leq 250-112[/tex]
[tex]7x\leq 138[/tex]
Divide by 7 both sides
[tex]x\leq 19.7[/tex]
therefore
The maximum number of volleyballs that she can buy is 19
