Question

How much is saved by buying a 20lb bag of brown sugar for $10.95 instead of 20 1 lb bags for $.89 each

Answer 1

Step 1

Karl has 12lbs of cat food.

To find how many 1/4lb servings of cat food he can get we do

`(12)/(x)\text{ =}(1)/(4)lb\text{ }`
`x=\text{ 48, }(1)/(4)\text{ lb servings of cat food}`

Step 2

Yes, I will agree with Karl's reasoning based on 1/4 lb servings of dog food and cat food.

`\begin{gathered} To\text{ find out how many 1/4lb of dog food we will get we do} \\ (20)/(y)=(1)/(4)lb \\ y\text{ = 80, }(1)/(4)\text{lb servings of dog food} \end{gathered}`

80 1/4lb servings of dog food is greater than 48 1/4lb servings of cat food.
