Question

Joseph is shopping for school supplies. He can buy a box of 24 pens for $4.32 or a box of

36 pens for $5.76. Which is a better buy? Show your reasoning.

Answer 1

The box of 36 pens for $5.76 is the better buy

Explanation:

To find which is a better buy, find which one has the lower cost per pen.

Find this for each box by dividing the price by the number of pens:

4.32/24

= 0.18

5.76/36

= 0.16

Since 0.16 is smaller than 0.18, this means the second box has the lower cost per pen.

So, the box of 36 pens for $5.76 is the better buy

Answer 2

Explanation:

Calculate the value of each pen for each price:

`(432)/(24) =18\\(576)/(36) =16`

The 36 box of pens in a better buy since each pen costs less
