Answer:

A. $1.50

Explanation:

You can probably read the cost from the graph. Find the x-axis position corresponding to 1 pen and locate the point on the graph above that position. Then read the y-coordinate (cost) from the vertical axis. It will be sufficiently close to $1.50 that you can easily determine that to be the correct answer choice.

__

Cost per pen is found by dividing cost by pens.

$4.50/(3 pens) = $1.50 /pen*

_____

* /pen would be pronounced, "per pen."
