Question

You buy 2 boxes of dog food and 1 can of car food for $24 Your friend buys 1 box of dog food and 2 cans of cat food for $24. Each box of dog food is $___ and each can of cat food cost $______.

Answer 1

a= $9

Explanation:

a = dog food, b = cat food

1a + 2b= 25

2a + 1b = 26

2a + 4b=50

2a + 1b = 26

2a - 2a = 0

4b - 1b = 3b

50 - 26 = 24

3b = 24

b = $8

1a + 2(8) = 25

25-16 = 9

a= $9
