Answer:
2x + 9y = 60
10x + 5y = 60
The price of each bag of popcorn is $6.
Step-by-step explanation:
Let each drink costs $x and the price of each bag of popcorn is $y.
So, from the given two conditions we can write two different equations as
2x + 9y = 60 ............... (1) and
10x + 5y = 60 ................. (2)
Now, solving those two equations we get,
5(60 - 9y) + 5y = 60
⇒ 300 - 45y + 5y = 60
⇒ 40y = 240
⇒ y = 6
Therefore, the price of each bag of popcorn is $6. (Answer)
