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

Step-by-step 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 :-

$2\times1.25+3\times x=2.5+3x$

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]
