q= quarts of strawberries.
You have to solve for q by balancing the equation. 2.50 is really being multiplied by 2.50, so you would divide it on the other side for the quart of strawberries.
Balance the equation.
2.50q=10
Divide both sides by 2.50.
2.50(/2.50)q= 10(/2.50)
q=4
There are 4 quarts of strawberries.
I hope this helps!
