Answer:
$6 dollars per steak
Explanation:
Ricky has used a total of $90, this means that whatever he buys must all add up to $90. He then uses $30, so that would mean if he subtracted the fruit price from the total price he would have the rest of the money to buy meat. He now has $60 for meat, and he bought 10 steaks. That would mean if you divided the price by how many steaks he bought he would get the price of each steak.
$90=$30+10x
-$30 -$30
$60= 10x
÷10 ÷10
$6=x
