Kallie Tran, owner of Flower Petal, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, Tran wants to set the del 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 (Click the icon to view the data.) Use the high-low method to determine Flower Petal'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). Variable cost (slope) Now determine the formula that is used to calculate the fixed cost component =Fixed cost Use the high-low method to determine Flower Petal's operating cost equation. (Round the variable cost to the nearest cent and the fixed cost to the nearest whole dollar.) y Use the operating cost equation you determined above to predict van operating costs at a volume of 15,500 miles.
