Kaitlyn Battle, owner of Rose Ready, operates a local chain of floral shops. Each shop has its own delivery van Instead of charging a flat delivery tee, Battle wants to set the delivery fee based on the distance driven to deliver the flowers Battle 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 vew the data ) Use the high-low method to determine Rose Ready's cost equation for van operating costs Use your results to predict van operating costs at a volume of 15,000 miles Let's begn by determining the formula that is used to calculate the variable cost (slope) Variable cost (slope) Now determine the formula that is used to calculate the fixod cost component # Fixed cost Use the high-low method to determine Rose Ready's operating cost equation (Round the vaniable cost to the nearest cent and the txed cost to the nearest whole dollar) Use the operating cost equation you determined above to predict van operating costs at a volume of 15,000 miles The operating costs at a volume of 15,000 miles is s
