Demaree is selling popcorn for three dollars a bag. He already has $40 and his go to her and 85 total. Use arithmetic to determine how many bags he needs to sell to make his goal.

Answer 1

To reach his goal, Demaree needs to sell enough bags of popcorn to make an additional $85. He already has $40, so he needs to make a total of $85 + $40 = $<<85+40=125>>125.
Since each bag is sold for $3, Demaree needs to sell $125 / $3 = <<125/3=41.67>>41.67 bags of popcorn.
Since he can't sell a fraction of a bag, Demaree needs to sell 42 bags of popcorn to make his goal.
