Damari is selling popcorn for $3 a bag. He already has $40, and his goal is to earn $85 total. Use arithmetic to determine how many bags he needs to sell to make his goal.
Options:
28
205
15
135
Let's start by finding out how much money Damari needs to earn to reach his goal: $85 - $40 = $<<85-40=45>>45
Next, divide the amount Damari needs to earn by the price of each bag of popcorn: $45 รท $3/bag = <<45/3=15>>15 bags
Damari needs to sell 15 bags of popcorn to make his goal, so the correct answer is 15.
