Karen Woo, owner of Flower Hour, 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 delivery distance affects these costs. 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 Hour's cost equation for van operating costs. Use your results to predict van operating costs at a volume of 16,000 miles. Let's begin by determining the formula that is used to calculate the variable cost (slope). Now determine the formula that is used to calculate the fixed cost component. Use the high-low method to determine Flower Hour's operating cost equation. (Round the variable cost to the nearest cent and the fixed cost to the nearest whole dollar.) y=x+ Use the operating cost equation you determined above to predict van operating costs at a volume of 16,000 miles. The operating costs at a volume of 16,000 miles is Data table
