damari is selling popcorn for 3 a bag he alreadey has 40 and his goal is to earn 85 total
To find the number of bags of popcorn Damari needs to sell to reach his goal, we need to subtract the number of bags he already has from his goal and then divide that by the price per bag.
Number of bags needed = (Goal - Bags already have) / Price per bag
Number of bags needed = (85 - 40) / 3
Number of bags needed = 45 / 3
Number of bags needed = 15
Damari needs to sell 15 bags of popcorn to reach his goal.
