Give the step-by-step reasoning process and then the final answer. Dylan filled his glass with ice cubes before he poured his soda into it. He counted and there were 8 ice cubes in his glass. Later when he prepares a pitcher of lemonade he puts two times as many ice cubes in the pitcher. Then it is time to refill the ice cube trays which have 12 spaces each for ice cubes. How many trays does Dylan need to fill if he used exactly all the ice they had in them?
Dylan uses 8 ice cubes in his glass plus 2 x as many for the pitcher of lemonade, 8 x 2 = 16 ice cubes. Those 16 ice cubes + the 8 before means that the ice cube trays originally held 16 + 8 ice cubes = 24 ice cubes. Each ice cube tray holds 12 ice cubes, 24 ice cubes / 12 spaces in the trays = 2 total ice cube trays.
The final answer: 2.
