Question

9. A movie theater sells small and large pretzels. A small pretzel costs $2. A large pretzel costs $4.50. A total of 50

Answer 1

Answer:

30 small pretzels were sold that night.

Step-by-step explanation:

x = small pretzels

y = large pretzels

x + y = 50

2x + 4.5y = 150

x + y - y = 50 - y

x = 50 - y

2(50 - y) + 4.5y = 150

100 - 2y + 4.5y = 150

2.5y = 50

2.5 2.5

y = 20

x + 20 = 50

x + 20 - 20 = 50 - 20

x = 30
