Question

The grocery store is having a sale on frozen vegetables. 4 bags are being sold for $5. At this rate, what is the cost of 7 bags??

Answer 1

$8.75

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 :)

Answer 2

$8.75

Explanation:

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

`(4)/(5)` =
`(7)/(x)`

Cross multiply and solve for x:

4x = 35

x = 8.75

So, the cost of 7 bags is $8.75
