Question 927445: A store sells tents, sleeping bags, and camp stools. A customer buys a tent, 3 sleeping bags, and 3 camp stools for $141. The price of the tent is 9 times the cost of a camp stool. The cost of a sleeping bag is $7 more than the cost of a camp stool. Find the cost of each item. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = dollar cost of tent
y = dollar cost of bag
z = dollar cost of stool
---
x + 3y + 3z = 141
x = 9z
y = z + 7
---
put the system of linear equations into standard form
---
x + 3y + 3z = 141
x - 9z = 0
y - z = 7
---
