Answer:
<em>7x+12y ≤ 600</em>
<h2><em>
or</em></h2>
<em>7x+12y = 600</em>
Step-by-step explanation:
<u><em>Lets first call</em></u><u><em> cars x and minivans y.</em></u><u><em> Since they want to raise 600, you </em></u><u><em>can do the sign ≤ and 600</em></u>
<u><em>≤ 600</em></u>
<u><em>Since it is </em></u><u><em>$7 per car, we can do 7x.</em></u>
<u><em>Since it is </em></u><u><em>$12 per minivan, we can do 12y.</em></u>
<u><em>Together, they have to </em></u><u><em>add up to 600 or more</em></u><u><em>.</em></u>
<u><em>7x+12y ≤ 600</em></u>
<u><em>If you provide some options, I might be able to give a better answer. Without options, I can't tell if they want an exact answer or not. So technically, the answer could also be:</em></u>
<u><em>7x+12y = 600</em></u>
