A gym teacher has 250 to spend on volleyball, she buys for volleyball nets that cost $28 volleyballs are $7 each.how many volley

MaRussiya [10]

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:

she can buy maximum of 19 balls.

Step-by-step explanation:

Let the number of volleyballs be x

we know that

$\text{(The cost of each volleyball net} \times \text{number of volleyball net)}+\text{(the cost of each volleyball} \times \text{number of volleyballs)}\leq \ 250$

so substituting the values,

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

$112 + 7x \leq 250$

$7x \leq 250 - 112$

$7x \leq 138$

$x \leq \frac{138}{7}$

$x \leq 19.7$
