Page collects fancy shoes and has 80 pairs in her closet. She decides to donate 30% of her collection that she no longer wears. After dropping off her donation, she treats herself and buys 6 more pairs to add to her collection. How many shoes does she have now? Give the rationale and then the answer.
Let's think step by step. She donates 30% of her 80 pairs of shoes so that’s .30 * 80 = 24 pair of shoes she donates. She had 80 shoes in her collection and donates 24 so that leaves 80 - 24 = 56 pairs of shoes. She now has 56 pairs of shoes and buys 6 more pairs so her collection is now 56 + 6 = 62 pairs of shoes.. The answer is: 62.

Sam shared a sum of money between his three cousins Sandra, Amy and Ruth in the ratio 2:1:3 respectively. If Amy got $50, how much did Sandra get? Give the rationale and then the answer.
Let's think step by step. Going by the ratio, for every 1 part that Amy gets, Sandra will get 2 parts. Since Amy got $50, Sandra will get 2 * $50 = $100.. The answer is: 100.

Wendi brought home 4 chickens. After a few days, she brought home enough additional chickens to double the number of chickens she owned. Then, a neighbor's dog ate one of her chickens. Finally, Wendi found an additional 4 less than ten chickens and brought them home too. After this, how many chickens does Wendi have? Give the rationale and then the answer.
Let's think step by step. Wendi doubled her number of chickens from 4 to 4 * 2 = 8 chickens. After a dog ate one of the chickens, 8 - 1 = 7 chickens remained. 4 less than 10 is 10 - 4 = 6. Therefore, Wendi added another 4 less than ten chickens for a total of 7 + 6 = 13 chickens.. The answer is: 13.
