Answer:

$8.75

Step-by-step explanation:

Create a proportion where x is the cost for 7 bags:

[tex]\frac{4}{5}[/tex] = [tex]\frac{7}{x}[/tex]

Cross multiply and solve for x:

4x = 35

x = 8.75

So, the cost of 7 bags is $8.75

Answer:

$8.75

Step-by-step explanation:

4 bags are being sold for $5 and the charge does not change,

so 1 bag is being sold at $5/4 bags = 1.25 (dollars/bag)

so 7 bags would cost 7 bags * (1.25 dollars / bag) = $8.75

Done :)
