Variables
Variables are letters use to represent number in an equation. Therefore,
Let
- x = cost of small bag of popcorn
- y = cost of large bag of popcorn
A large bag of popcorn cost $3.50 more than a small bag of popcorn. Therefore,
- y = 3.50 + x
A movie theatre sells 12 large bags of popcorn and 25 small bags of popcorn for $227. Therefore,
- 12y + 25x = 227
Let's combine the equation
y - x = 3.50
12y + 25x = 227
12y - 12x = 42
37x = 185
x = 185 / 37
x = 5
Therefore,
y = 3.50 + 5
y = 8.50
