Kara Woo, owner of Flower Power, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, Woo wants to set the delivery fee based on the distance driven to deliver the flowers. Woo wants to separate the fixed and variable portions of her van operating costs so that she has a better idea how deliv- ery distance affects these costs. She has the following data from the past seven months: Month January February March April... May..... June.. July Miles Driven 16,000 17,500 14,900 16,200 16,900 15,100 14,500 Van Operating Costs $5,490 $5,700 $4,910 $5,340 $5,820 $5,410 $4,920 E6-27A Continuation of E6-26A: High-low method (Learning Objective 4) Refer to Flower Power's data in E6-26A. Use the high-low method to determine Flower Power's cost equation for van operating costs. Use your results to predict van operating costs at a volume of 16,000 miles
