Question

A student bought two juice pouches for $1.25 each and 3 bags of chips. The total cost was $5.05. Write and solve an equation to determine the cost of a single bag of chips, c.

Remember money is rounded to the nearest hundtedth.

Answer 1

1.25+3x=5.05

3x=5.05-1.25

3x=3.8

divide 3.8 by 3 and you get 1.27 so x=1.27
and that’s how much a bag of chips cost

Answer 2

$0.85

Explanation:

2 juice pouches- $2.50

3c+2.50=5.05 (c is for bags of chips)

3c=5.05-2.50

3c=2.55

c= $0.85

So one bag of chip is $0.85
