Two families attended a baseball game. The first family bought 5 bags of popcorn and 6 souvenir cups, which totaled $65. The second family bought 10 bags of popcorn and 4 souvenir cups, which totaled $90. How much did one bag of popcorn cost?

$4
$5
$6
$7

Both sides of the first equation need to be multiplied by -4, and both sides of the second equation need to be multiplied by 5. We are asked for the price of 1 bag of popcorn, x, so we will eliminate y and solve for x.

-16x - 20y = -200

30x + 20y = 270

In conclusion, Simply adding the equations will get rid of y.

14x = 70

x = 70/14

x = 5
