Damari is selling popcorn for $3 a bag. He already has $40, and his goal is to earn $85 total. Use arithmetic to determ how many bags he needs to sell to make his goal.

Answer 1

Let's represent the number of bags Damari needs to sell as 'x'.

Since each bag is sold for $3, the total amount Damari earns from selling x bags is 3x.

We are given that Damari already has $40, so the total amount he needs to earn is $85.

Therefore, we can set up the equation:
40 + 3x = 85

To solve for x, we can subtract 40 from both sides of the equation:
3x = 85 - 40
3x = 45

Finally, we divide both sides of the equation by 3 to solve for x:
x = 45/3
x = <<15=15>>15

Damari needs to sell 15 bags in order to make his goal.
