Question

Jacob needs 48 ounces of tomatoes for the spaghetti sauce he is choosing between the two brands shown explain how Jacob can determine which is the better value. Brand A is: 8 oz ($2.99) Brand B is : 16 oz ($4.99)

Answer 1

We know that he needs 48 oz of tomatoes.

Let be "x" the cost in dollars of 48 ounces of Brand A.

We know tha 8 ounces cost $2.99 in Brand A, so we can set up the following proportion:

`(2.99)/(8)=(x)/(48)`

Now we must solve for "x":

`\begin{gathered} (48)((2.99)/(8))=x \\ x=17.94 \end{gathered}`

Let be "y" the cost in dollars of 48 ounces of Brand B.

We know that 16 ounces cost $4.99 in Brand B, so we can set up the following proportion:

`(4.99)/(16)=(y)/(48)`

Solving for "y", we get:

`\begin{gathered} (48)((4.99)/(16))=y \\ y=14.97 \end{gathered}`

Therefore, as you can see, if he chooses Brand A,he'd pay $17.94 and if he chooses Brand B, he'd pay $14.97. So you can conclude that the better value is: Brand B.
