Question: A business executive is going on a four day vacation where he will be unable to answer emails. The first day he is gone, he receives 16 new emails. On each of the following days, he receives half as many new emails as he received on the prior day. At the end of his four day vacation, how many new emails will he have received in total?
Answer: On the second day, the executive receives 16 / 2 = 8 new emails. On the third day, he receives 8 / 2 = 4 new emails. On the fourth day, he receives 4 / 2 = 2 new emails. Therefore, during the entire trip he will have received 16 + 8 + 4 + 2 = 30 new emails. The answer is 30.
[Question]Last week, a farmer shipped 10 boxes of pomelos which had 240 pomelos in all. This week, the farmer shipped 20 boxes. How many dozens of pomelos did the farmer ship in all?
[Answer]There were 240 / 10 = 24 pomelos in a box. This means that each box has 24 / 12 = 2 dozens of pomelos since 1 dozen is equal to 12. The farmer shipped a total of 10 + 20 = 30 boxes. Thus, the farmer shipped a total of 30 x 2 = 60 dozens of pomelos. The answer is 60.
[Question]Whitney’s mom gave her two $20 bills to spend at the school book fair. Whitney has decided to buy 2 posters, 3 notebooks, and 2 bookmarks. Each poster costs $5, each notebook costs $4, and each bookmark costs $2. How much money, in dollars, will Whitney have left over after the purchase?
[Answer]
Whitney is buying 2 posters for $5 each, so the posters will cost 2 * $5 = $10 total cost for posters. Whitney is buying 3 notebooks for $4 each, so the notebooks will cost 3 * $4 = $12 total cost for notebooks. Whitney is buying 2 notebooks for $2, so the bookmarks 2 * $2 = $4 total cost for bookmarks. Since Whitney is paying $10 for posters, $12 for notebooks, and $4 for bookmarks, her total purchase will cost $10 + $12 + $4 = $26 total purchase cost. Whitney’s mom gave her 2 $20 bills, so she will be paying with 2 * $20 = $40 total payment. Since Whitney is paying with $40 and her purchase cost will be $26, she will have $40 - $26 = $14 left over after the purchase. The answer is 14.
