Question

Six cans of soda and two bags of potato chips cost $7.08. And eight cans of soda and five bags of potato chips cost $12.45.What is the price per can for the soda, and price per bag of potato chips?

Answer 1

6s + 2p = $ 7.08 ( 1)
8s + 5p = $12.45 ( 2)

Multiply the first ( 1) for 5/2:
15s + 5p = 17.7 ( 3)

( 3) - ( 2):
-> 7s = 5.25
=> s = 5.25/ 7 = .75
Thus the cost per soda is 75 cents.

Can you find the cost of potato?
