[Question]Apple sold 100 iPhones at their New York store today for an average cost of $1000. They also sold 20 iPads for an average cost of $900 and 80 Apple TVs for an average cost of $200. What was the average cost across all products sold today?
[Answer]The sales for iPhones were 100 iPhones * $1000 per iPhone on average = $100,000. The sales for iPads today were 20 iPads * $900 per iPad = $18,000. The sales for Apple TV's today were 80 * $200 = $16,000. The total sales for Apple at their New York store today was $100,000 + $18,000 + $16,000 = $134,000. The total number of products sold was 100 + 20 + 80 = 200. The average cost per product sold was $134,000 total sales / 200 total products = $670. The answer is 670.
Q: Bonny just bought her 13th pair of shoes, which is 5 less than twice as many pairs of shoes as Becky owns. Bobby has 3 times as many pairs of shoes as Becky has. How many shoes does Bobby have?
A: Let x be the number of pairs of shoes that Becky owns. Since 13 pairs is 5 less than twice as many pairs as Becky owns, then the relationship is 2x - 5 = 13. Adding 5 to each side of the equation, we get 2x = 18. Solving for x, we get x = 9. Since Bobby has 3 times as many pairs of shoes as Becky has, then Becky has 3 * 9 = 27 pairs of shoes. The answer is 27.
Question: Donna can watch 8 episodes each day during weekdays. On each weekend day, she can watch three times the number of episodes she can watch on the weekdays. How many episodes can she watch in a week?

The total number of episodes she can watch every weekend is 24 x 2 = 48. Therefore, Donna can watch 40 + 48 = 88 episodes every week. The answer is 88.

Question: Leo had 400 marbles in a jar. He packed the marbles with ten marbles in each pack, and he gave some of them to his two friends, Manny and Neil. He gave Manny 1/4 of the number of packs of marbles, Neil received 1/8 of the number of packs of marbles, and he kept the rest. How many packs of marbles did Leo keep?
Answer:
Leo had 400 / 10 = 40 packs of marbles. He gave Manny 1 / 4 x 40 = 10 packs of marbles. And, Neil received 1 / 8 x 40 = 5 packs of marbles. Thus, Leo. gave a total of 10 + 5 = 15 packs of marbles. Therefore, Leo kept 40 - 15 = 25 packs of marbles. The answer is 25.
