[Question]A small pizza has 6 slices, a medium pizza has 8 slices whereas a large pizza has 12 slices. How many slices of pizza will you have if you bought a total of 15 pizzas and you know you ordered 4 small pizzas and 5 medium pizzas?
[Answer]We know that 4 small pizzas and 5 medium pizzas = 4 + 5 = 9 non - large pizzas were purchased. Because a total of 15 pizzas were purchased then 15 - 9 = 6 large pizzas were ordered. If 1 small pizza has 6 slices then 4 small pizzas will have 4 * 6 = 24 slices. Similarly, If 1 medium pizza has 8 slices then 5 medium pizzas will have 5 * 8 = 40 slices. Similarly, If 1 large pizza has 12 slices then 6 large pizzas will have 6 * 12 = 72 slices. That means in total we have 24 small slices + 40 medium slices + 72 large slices = 24 + 40 + 72 = 136 slices of pizza. The answer is 136.

[Question]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?
[Answer]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 answer is 2.

[Question]Bob has a cube of silver that measures 3 inches on each side. A cubic inch of silver weighs 6 ounces. Each ounce of silver sells for $25. He sells it for 110% of its silver value. How much does he sell it for?
[Answer]The silver has a volume of 3 * 3 * 3 = 27 cubic inches. So it weighs 27 * 6 = 162 ounces. So its value is 162 * 25 = $4050. That means he sold it for 4050 * 1.1 = $4455. The answer is 4455.

[Question]A tank contains 6000 liters of water, 2000 liters evaporated, and then 3500 liters were drained by Bob. How many liters are in the tank if it now rains for 30 minutes and every 10 minutes 350 liters of rain are added to the tank?
[Answer]
After the first evaporation, the water tank has 6000 liters - 2000 liters = 4000 liters. After the second extraction, the water tank has 4000 liters - 3500 liters = 500 liters. The tank is refilled with rain 30 minutes / 10 minutes = 3 times. The amount of water refilled with rain is 3 times * 350 liters per time = 1050 liters. With the additional rainwater, the water tank has 500 liters + 1050 liters = 1550 liters. The answer is 1550.
