Answer: Hello there!
We want to write a problem where:
q=quarts of strawberries
2.50q=10
Ok, suppose this problem
"John is buying strawberries, every quart of strawberries costs $2.50, what is the number of quarts that john buys if the final price is $10?"
this problem is solved with the equation:
$2.50*q = $10
q = 10/2.50 = 4
John buys 4 quarts of strawberries.
