Final answer:
Damari needs to sell 15 more bags of popcorn at $3 each to reach his goal of $85, as he already has $40.
Step-by-step explanation:
The student is asking how many bags of popcorn Damari needs to sell to reach his goal of $85, given that he already has $40 and each bag sells for $3. To find this out, we'll subtract the amount he already has from his goal to determine how much more he needs to earn. We then divide that amount by the cost per bag.
First, we calculate the additional amount Damari needs to make:
$85 (goal) - $40 (current amount) = $45 needed
Next, we determine how many bags of popcorn he must sell to make the remaining $45:
$45 needed ÷ $3 per bag = 15 bags to be sold
Damari needs to sell 15 more bags of popcorn to reach his goal of $85.
