<h3><u>Answer:</u></h3>
variable : c (cost of 1 bag of chips )
equation: 2.5 + 3c = 5.05
solution: cost of 1 bag of chips = $ 0.85 and cost of 3 bags of chips = $ 2.55
<h3><u>Solution:</u></h3>
Given that, student bought two juice pouches for $1.25 each and 3 bags of chips
Let "c" be the price of 1 bags of chips
cost of 1 juice pouches = $ 1.25
Total cost = $ 5.05
<em><u>Therefore, we frame a equation as:</u></em>
two juice pouches x cost of 1 juice pouches + 3 bags of chips x price of 1 bags of chips = 5.05
![2 \times 1.25 +3\times c = 5.05](https://tex.z-dn.net/?f=2%20%5Ctimes%201.25%20%2B3%5Ctimes%20c%20%3D%205.05)
<em><u>Solve the above equation for "c"</u></em>
![2.5 + 3c = 5.05\\\\3c = 5.05 - 2.5\\\\3c = 2.55\\\\c = 0.85](https://tex.z-dn.net/?f=2.5%20%2B%203c%20%3D%205.05%5C%5C%5C%5C3c%20%3D%205.05%20-%202.5%5C%5C%5C%5C3c%20%3D%202.55%5C%5C%5C%5Cc%20%3D%200.85)
Thus cost of 1 bag of chips = $ 0.85
Thus, cost of 3 bags of chips = $ 0.85 x 3 = $ 2.55
