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 :-
[tex]2\times1.25+3\times x=2.5+3x[/tex]
Since, the total cost was $5.05.
Then, the equation to determine the cost of a bag of chips would be :-
[tex]2.5+3x=5.05[/tex]
Subtract 2.5 from both sides , we get
[tex]3x=2.55[/tex]
Divide both side by 3 , we get
[tex]x=0.85[/tex]
Hence, the cost of a bag of chips= $0.85 or 85 cents [∵ 1 dollar = 100 cents]
