Answer:
3x + y + 2z = 25
2x + 3y + 3z = 30
2x + 2y + 4z = 25
Explanation:
Let x, y and z represent the price ( in dollars ) of each hot dog, each pretzel and each snow cones respectively,
So, Price of 3 hot dogs, 1 pretzel, and 2 snow cones = 3x + y + 2z,
Price of 2 hot dogs, 3 pretzels, and 3 snow cones = 2x + 3y + 3z
And, price of 2 hot dogs, 2 pretzels, and 4 snow cones = 2x + 2y + 4z
According to the question,
3x + y + 2z = 25
2x + 3y + 3z = 30
2x + 2y + 4z = 25
Which is the required system of equations.
