Damari is selling popcorn for 3$ a bag he already has 40$ and his goal is to earn 85$ total use arithmetic to determin how many bags he needs to sell
To determine how many bags Damari needs to sell, we can subtract the amount he already has from his goal.
Damari already has $40 and his goal is to earn $85 total.
$85 - $40 = $45
Since Damari is selling each bag for $3, we can divide the remaining amount needed by the price per bag to determine how many bags he needs to sell.
$45 รท $3 = 15
Therefore, Damari needs to sell 15 bags in order to reach his goal of $85.
