Answer:
$18
Step-by-step explanation:
First you would multiply $1.50 by how many cups of lemonade they sell (20). Your answer for this would be $30. After that you want to subtract the $12 from the $30, because they spent $12 on materials. Then you get $18, which is your answer. Hope this helps :)
$30 is how much they made in total, 30-12= $18 which is their profit.
