Damari is selling popcorn for 3$ a bag. He already has 40$, and his goal is to earn 85$. How many bags does he need to sell to get to his goal

1 answer

Damari needs to earn an additional $85 - $40 = $<<85-40=45>>45.
Therefore, he needs to sell $45 / $3 = <<45/3=15>>15 bags of popcorn. Answer: \boxed{15}.
