Question

The gym teacher has $250 to spend on volleyball equipment. She buys 4 volleyball nets for $28 each. Volleyballs cost $7 each. How many volley balls can she buy

Answer 1

The maximum number of volleyballs that she can buy is 19

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

`28(4)+7x\leq 250`

Solve for x

`112+7x\leq 250`

subtract 112 both sides

`7x\leq 250-112`

`7x\leq 138`

Divide by 7 both sides

`x\leq 19.7`

therefore

The maximum number of volleyballs that she can buy is 19
