Betty had $40 in her pocket. She bought 12 identical bags of popcorn. Betty was left with $10 after buying the popcorn. What was the price, in dollars, of each bag of popcorn?
Each bag of popcorn costs $2. 5 You can solve it by creating an equation. This one can be: 40 -12x = 10 Undo the operation. 40 -12x = 10 -40 -12x = 10 -40 Eliminate the 40. This will live you with the following. -12x = -30 Divide -12x by -12. Do the same with the -30 -12x = -30/ -12 This will give you the answer. x = 2.5
