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
[tex]\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[/tex]
so substituting the values,
[tex]28(4) + 7x \leq 250[/tex]
[tex]112 + 7x \leq 250[/tex]
[tex] 7x \leq 250 - 112[/tex]
[tex] 7x \leq 138[/tex]
[tex] x \leq \frac{138}{7}[/tex]
[tex] x \leq 19.7[/tex]
