Kerri Battle, the owner of Tulip Time, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, the Battle wants to set the delivery fee based on the distance driven to deliver the flowers. The battle wants to separate the fixed and variable portions of her van operating costs so that she has a better idea of how delivery distance affect these costs.

May 16,500 $5,450
June 15,200 $5,230
July 14,400 $4,680
