Question 927459: A vendor sells hot dogs, bags of potato chips, and soft drinks. A customer buys 5 hot dogs, 2 bags of potato chips, and 4 soft drinks for $16.50. The price of a hot dog is $2.00 more than the price of a bag of potato chips. The cost of a soft drink is $4.25 less than the price of two hot dogs. Find the cost of each item. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = $/dog
y = $/chip
z = $/drink
---
5x + 2y + 4z = 16.50
x = y + 2
z = 2x - 4.25
---
put the system of linear equations into standard form
---
5x + 2y + 4z = 16.50
x - y = 2
2x - z = 4.25
---
copy and paste the above standard form linear equations in to this solver:
