An ice cream factory makes 260 quarts of ice cream in 10 hours. How many quarts could be made in 36 hours? What was that rate per day?

260 quarts * 36 hours = 9,360 quarts

260 * 20 hours = 5,200 quarts - - - > 260 quarts / 10 hours = 26 quarts per hour - - - > 26 quarts * 4 = 104 quarts - - - > 5,200 + 104 = 5,304 quarts per day
