Question: Every day in a week, Siena bookmarks 30 website pages from the research she does on her browser. If Siena has 400 bookmarked pages on her bookmarks library now, how many pages will she have in her bookmarks library at the end of March?
Answer: Since Siena bookmarks 30 website pages from the research she does on her browser every day, at the end of March, with 31 days, she would have bookmarked 30 * 31 = 930 pages. If Siena already has 400 bookmarked pages in her bookmarks library now, she will have 930 + 400 = 1330 pages in her bookmarks library at the end of March. The answer is 1330.

Question: An online newspaper had listed 100 visitors in October. The number of visitors in November increased by 15%. There were 15 more visitors in December than in November. What is the total number of visitors for these three months?
Answer: There was an increase of 100 x 15 / 100 = 15 visitors in November. So, the number of visitors in November was 100 + 15 = 115. In December, the number of visitors was 115 + 15 = 130. Therefore, a total of 100 + 115 + 130 = 345 visitors listed in these three months. The answer is 345.

Question: 2 tablespoons of popcorn kernels will make 4 cups of popcorn. For movie night, Joanie wants 3 cups of popcorn, Mitchell wants 4 cups of popcorn, Miles and Davis said they would split 6 cups of popcorn and Cliff said he would only eat 3 cups. How many tablespoons of popcorn kernels will they need?
Answer: If Joanie wants 3 cups, Mitchell wants 4 cups, Miles & Davis want 6 cups and Cliff wants 3 cups then they want 3 + 4 + 6 + 3 = 16 cups of popcorn. Every 2 tablespoons makes 4 cups and they want 16 cups so 16 / 4 = 4 groups of 2 tablespoons are needed. Thus they need 4 * 2 = 8 tablespoons in total. The answer is 8.

Question: A tractor trailer has a load of 50000 pounds. 10% of the weight gets unloaded at the first store, and 20% of the remaining load is removed at the second store. How much weight, in pounds, is left on the truck after the two deliveries?
Answer:
First Store:50000(.10) = 5000. 50000 - 5000 = 45000 pounds. Second Store:45000(.20) = 9000. 45000 - 9000 = 36000 pounds. The answer is 36000.
