Each Home Depot store must decide how much paint to order each month. From historical records, they know that the amount of paint they sell during May is distributed as follows: there is a 12% chance demand will be 620 gallons, a 17% chance that demand will be 850, a 35% chance that demand will be 1400, and otherwise, demand will be 1600 gallons. What is the expected value of demand for paint? (please express your answer using 2 decimal places)
