For 2016, Listello buys 260,000 marble tiles at an average cost of $2 per tile and sells them to retailers at an average price of $5 per tile. Assume Listello has no fixed costs and no inventories. Read the requirements. Requirement 1. Calculate Listello's operating income for 2016. Revenues Costs: Purchase cost of tiles Ordering costs Receiving and storage Shipping Total costs Operating income Requirements 1. Calculate Listello's operating income for 2016. For 2017, retailers are demanding a 4% discount off the 2016 price. Listello's suppliers are only willing to give a 3% discount. Listello expects to sell the same quantity of marble tiles in 2017 as in 2016. If all other costs and cost-driver information remain the same, calculate Listello's operating income for 2017. Suppose further that Listello decides to make changes in its ordering and receiving-and-storing practices. By placing long-run orders with its key suppliers, Listello expects to reduce the number of orders to 500 and the cost per order to $35 per order. By redesigning the layout of the warehouse and reconfiguring the crates in which the marble tiles are moved, Listello expects to reduce the number of loads moved to 3,925 and the cost per load moved to $38. Will Listello achieve its target operating income of $1.91 per tile in 2017? Show your calculations. i Data Table Cost Driver Activity 1. Placing and paying for orders of marble tiles 2.
