Answer 1

Given:

Size (oz) Cost ($)

3 0.99

8 2.59

16 5.69

32 11.89

To find:

The size package of pasta which has the lowest unit price.

Solution:

We know that,

`\text{Unit price}=\frac{\text{Total price}}{\text{Quantity}}`

Now, the unit prices for all size package of pasta are

`\text{Unit price}=(0.99)/(3)=0.33`

`\text{Unit price}=(2.59)/(8)=0.32375`

`\text{Unit price}=(5.69)/(16)=0.355625`

`\text{Unit price}=(11.89)/(32)=0.3715625`

Here, the lowest unit price is 0.32375. So, 8oz size package of pasta has the lowest unit price.

Therefore, the correct option is B.
