40 - 12x = 10
-12x = 10 - 40
-12x = - 30
x = -30/-12
x = 2.50...so each bag of popcorn is : $ 2.50
-12x = 10 - 40
-12x = - 30
x = -30/-12
x = 2.50...so each bag of popcorn is : $ 2.50
if you have $10 left then that means you only wasted 30, meaning each bag only cost $2.50.
2.50 x 12=30
2.50 x 12=30
