Kelly Smith, owner of Flower Paradise, operates a local chain of floral shops. Each shop has its own delivery van.

She has the following data from the past seven months: (Click the icon to view the data.) Use the high-low method to determine Flower Paradise's cost equation for van operating costs. Use your results to predict van operating costs at a volume of 15,500 miles. Let's begin by determining the formula that is used to calculate the variable cost (slope).
