Aniyah has 6 times as many birthday candles as Ambika. If Ambika has four birthday candles, how many birthday candles will they have if they put the birthday candles together and shared them equally between themselves? Give the rationale and then the answer.
Let's think step by step. If Ambika has four birthday candles, and Aniyah has 6 times as many birthday candles as Ambika, then Aniyah has 4 * 6 = 24 candles. When they put together the candles, the total number becomes 24 + 4 = 28 candles. When they divide the candles and share them equally, each person gets 28 / 2 = 14 birthday candles.. The answer is: 14.

Mason is cleaning out all the junk in his attic. 20% of the items are useful, 10% are valuable heirlooms, and 70% are junk. If Marcus's attic has 8 useful items in it, how many junk items does it have? Give the rationale and then the answer.
Let's think step by step. First find the total number of items in the attic by dividing the number of useful items by the percentage of useful items: 8 items / .2 = 40 items. Then multiply the total number of items by the percentage that are junk to find the number of junk items: 40 items * .7 = 28 items.. The answer is: 28.

Anna has 3 times as many toys as Mandy and 2 fewer toys than Amanda. If they have 142 toys all together, how many toys does Mandy have? Give the rationale and then the answer.
Let's think step by step. Let x be the number of toys Mandy has. Anna has 3 * x toys. Amanda has 3 * x + 2 toys. x + 3 * x + 3 * x + 2 = 142. 7 * x + 2 = 142. 7 * x = 140. x = 20.. The answer is: 20.
