Question

Abby can buy 8-pound bag of dog food for $7.40 or a 4-puond bag of the same dog food for $5.38.Which is the better buy?

Answer 1

We can find price of each case and then we can decide

Case-1:

Abby can buy 8-pound bag of dog food for $7.40

so, for 8 pound bag = $7.40

now, we can find price

`p=(7.40)/(8)`

`p=0.925`

Case-2:

a 4-puond bag of the same dog food for $5.38

So, for 4 pounds = $5.38

now, we can find price

`p=(5.38)/(4)`

`p=1.345`

So, we can see that cheapest price is $0.925 per pound

so, first case is better

so,

8-pound bag of dog food for $7.40..........Answer
