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 bag of chips

Answer 1

2(1.25)+3x=5.05
2.5+3x=5.05
3x=2.55
x=0.85

Answer 2

Answer: $0.85

Explanation:

Let the cost of a bag of chips be x.

Given : A student bought two juice pouches for $1.25 each and 3 bags of chips.

Then , the total cost will be :-

`2*1.25+3* x=2.5+3x`

Since, the total cost was $5.05.

Then, the equation to determine the cost of a bag of chips would be :-

`2.5+3x=5.05`

Subtract 2.5 from both sides , we get

`3x=2.55`

Divide both side by 3 , we get

`x=0.85`

Hence, the cost of a bag of chips= $0.85 or 85 cents [∵ 1 dollar = 100 cents]
