Answer:
The cost of a bag of chips is [tex]c=\$0.85[/tex]
Step-by-step explanation:
Let
c ----> the cost of a bag of chips
we know that
The cost of a juice pouch ($2.50) plus the cost of 3 bags of chips must be equal to $5.05
The cost of 3 bags of chips is equal to multiply 3 by its cost c
so
The linear equation that represent this situation is
[tex]2.50+3c=5.05[/tex]
solve for c
Subtract 2.50 both sides
[tex]3c=5.05-2.50[/tex]
[tex]3c=2.55[/tex]
Divide by 3 both sides
[tex]c=2.55/3[/tex]
[tex]c=\$0.85[/tex]
