To determine how many bags of popcorn Daman needs to sell to reach his goal, we need to calculate the difference between his goal amount and the amount he already has, and then divide that by the price he is selling each bag of popcorn for.

Daman's goal: $85
Amount he already has: $40

Amount he needs to earn: $85 - $40 = $45

Price per bag: $3

Number of bags he needs to sell: $45 / $3 per bag = 15 bags

Therefore, Daman needs to sell 15 bags of popcorn to reach his goal of $85.
