Answer:
The price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75
Step-by-step explanation:
We can solve by means of a 2x2 equation system, assuming that the question is the price of each product
We have to:
"x" price of drinks
"and" price of the bag of popcorn
9 * x + 4 * y = 40.5
3 * x + 5 * y = 38.25 => x = (38.25 - 5 * y) / 3
replacing:
9 * (38.25 - 5 * y) / 3 + 4 * y = 40.5
114.75 - 15 * y + 4 * y = 40.5
-11 * y = 40.5 - 114.75
y = -74.25 / -11
y = 6.75
now for x:
x = (38.25 - 5 * 6.75) / 3
x = 1.5
So the price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75
