1 answer

To determine how many bags Damari needs to sell to make his goal, we can subtract his current amount of money from his goal and divide it by the price of each bag.

Goal - Current amount = Amount needed to reach goal

$85 - $40 = $45

$45 / $3 = 15

Damari needs to sell 15 bags of popcorn to make his goal.

The correct answer is A. 15.
