Lance wants to finish reading a 100 page book in 3 days. Yesterday, he started to read 35 pages. Today, he read 5 fewer pages than yesterday. How many pages should he read tomorrow to finish the book?
Let's think: Lance read 35 - 5 = 30 pages today. So he read a total of 35 + 30 = 65 pages in 2 days. Thus, he should read 100 - 65 = 35 pages tomorrow.. The answer is: 35.

Sally sold 20 cups of lemonade last week. She sold 30% more lemonade this week. How many cups of lemonade did she sell in total for both weeks?
Let's think: If Sally sold 30% more lemonade this week, she sold 20 * 30 / 100 = 6 more cups this week. This week, Sally sold 20 + 6 = 26 cups of lemonade. In total for both weeks, Sally sold 20 + 26 = 46 cups of lemonade.. The answer is: 46.

Miss Smith is teaching second period English and is shocked at how small the class seems. There are 6 tables in the classroom with 3 students currently sitting at each table. Sally said 3 girls went to the bathroom, and three times more students went to the canteen. Elliott said that 2 groups of students have recently been added to their class, and each group has 4 students in it. None of these students are in the class right now. Lucas pointed out that a few foreign exchange students have joined the class; 3 from Germany, 3 from France, and 3 from Norway. These students are also missing. How many students are supposed to be in the class?
Let's think: There are currently 3 * 6 = 18 students sitting in the classroom. There were 3 * 3 = 9 students who went to the canteen. Sally has therefore noticed 3 + 9 = 12 students missing from the class. Elliott said that 2 groups of students have joined the class, so there are another 2 * 4 = 8 students who are not in the classroom. Lucas said that there are 3 + 3 + 3 = 9 foreign exchange students who are not in the classroom. Therefore, there should be 18 + 12 + 8 + 9 = 47 students.. The answer is: 47.

A store sold a certain brand of jeans for $40. They only have few pairs of jeans left so they decided to give 10% discount on every two pairs of jeans bought by a customer at any one time. How much will a customer pay for 3 pairs of jeans?
Let's think:
Two pairs of jeans cost $40 x 2 = $80. A discount of $80 x 10 / 100 = $8 will be given for this. Hence, the cost of two pairs of jeans will now be $80 - $8 = $72. Therefore, the customer will pay $72 + $40 = $112 for the three pairs of jeans.. The answer is: 112.
