3. Pam just got a shipment of pens and told Erin to hand them out and put in the
computer how much the shipment cost. Erin is nervous about this and wants to
make sure she gets it right. There are 15 coworkers and they each received 5 pens.
There are 8 pens per package, at $2.65 per package. What was the total cost of the pen shipment?
