To find out how many bags of popcorn Damari needs to sell to reach his goal of $85, we can set up the equation based on his current amount of money and the price of each bag of popcorn.
- Damari currently has $40.
- He wants to reach a total of $85.
- Each bag of popcorn sells for $3.
First, we calculate how much more money he needs to earn to reach his goal:
\[ 85 - 40 = 45 \]
Now, we determine how many bags of popcorn he needs to sell to earn that additional $45:
\[ \frac{45}{3} = 15 \]
So, Damari needs to sell 15 bags of popcorn to reach his goal of $85.
Correct response: 15
