The lights in Malcolm’s house are flickering, and he hopes that replacing all of his white lights with colored lights will make it stop. He buys 12 red lights, 3 times as many blue lights, and 6 green lights. If he still has 5 colored lights left to buy, how many white lights did Malcolm have initially? Give the rationale and then the answer.
Let's think step by step. Malcolm has bought 12 * 3 = 36 blue lights. This means he has bought a total of 12 + 36 + 6 = 54 colored lights. If he still needs to buy more lights, then he must have initially had 54 + 5 = 59 white lights.. The answer is: 59.

In one day, Ella's dog eats 4 pounds of food for every one pound of food that Ella eats. How much food do Ella and her dog in 10 days if Ella eat 20 pounds of food each day? Give the rationale and then the answer.
Let's think step by step. If Ella's dog eats 4 pounds of food for every one pound of food that Ella eats, when Ella eats 20 pounds of food in a day, Ella's dog eats 4 * 20 = 80 pounds of food. Together, in one day, Ella and her dog eats 80 + 20 = 100 pounds. In 10 days, Ella and her dog will eat 10 * 100 = 1000 pounds of food.. The answer is: 1000.

Raine's house is just a walking distance from her school. It takes her 150 steps to walk to the school. How many steps does she take walking to and from school in five days? Give the rationale and then the answer.
Let's think step by step. Raine takes 150 x 2 = 300 steps walking to and from school each day. Thus, it takes her 300 x 5 = 1500 steps in five days.. The answer is: 1500.
