During one hour, Tom can read 12 pages of a book. How many pages would he be able to read during 2 hours if he could increase his reading speed by a factor of 3?

If Tom could triple his reading speed, he could read 12 * 3 =

<<12*3=36>>36 pages of a book in one hour. Therefore, during two hours he could read 36 * 2 = <<36*2=72>>72 pages. #### 72 I went to the music shop and there were CDs of The Life Journey for $100, A Day a Life for $50, and When You Rescind for $85 on display. If I bought 3 of each CD to share with my friends, what's the total amount of money I spent in the shop? The total cost of The Life Journey is 3 × $100 = $<<3*100=300>>300. The total cost of When You Rescind is 3 × $85 = $<<3*85=255>>255. The total cost of A Day a Life is 3 × $50 = $<<3*50=150>>150. The total cost for all the CDs is $150 + $255 + $300 = $<<150+255+300=705>>705. #### 705 Melissa wants to make some dresses to sell at the upcoming festival. She has 56 square meters of fabric to make them. She knows that each dress takes 4 square meters of fabric and 3 hours to make. How many hours does she have to work? Each dress takes 4 square meters of fabric to make, so the number of dresses she can make will be 56/4 = <<56/4=14>>14 dresses. Each dress takes 3 hours to make, thus she will have to work 14 dresses x 3 hours/dress = <<14*3=42>>42 hours. #### 42 A zoo has 8 parrots. It 3 times the number of snakes than parrots and 2 times the number of monkeys than snakes. The number of elephants is half the number of parrots and snakes added up, and there are 3 fewer zebras than elephants. What is the difference in number between the zebras and the monkeys? The zoo has 8 x 3 = <<8*3=24>>24 snakes. It has 24 x 2 = <<24*2=48>>48 monkeys. The number of parrots and snakes added up is 8 + 24 = <<8+24=32>>32 There are 32/2 = <<32/2=16>>16 elephants. There are 16 - 3 = <<16-3=13>>13 zebras. The difference between zebras and monkeys is 48 - 13 = <<48-13=35>>35 #### 35 The county fair was hosting a pumpkin contest to see who could grow the biggest pumpkin in pounds. Brad entered his pumpkin with a weight of 54 pounds. Jessica's was half the weight of Brad's. Betty's pumpkin weight 4 times the amount of Jessica's pumpkin. What is the difference between the heaviest and lightest pumpkin in pounds? Jessica's pumpkin weighs half the weight of Brad's 54-pound pumpkin so 54/2 = <<54/2=27>>27 pounds Betty's pumpkin weighs 4 times the amount of Jessica's 27-pound pumpkin so it weighs 4*27 = <<4*27=108>>108 Betty has the heaviest pumpkin at 108 pounds while Jessica's is the lowest at 27 pounds so the difference is 108-27 =<<108-27=81>>81 pounds #### 81 On a particular week, Fatima's restaurant served 25 people food and drinks, and 3/5 of that number came to buy coffee. How many people did not buy coffee in the restaurant? The number of customers who were served coffee in the restaurant is 3/5*25 = <<3/5*25=15>>15 If the total number of customers who came to the restaurant was 25, then 25-15 = <<25-15=10>>10 customers did not buy coffee #### 10 John writes 3 stories every week. Each short story is 50 pages. He also writes a novel that is 1200 pages each year. Each sheet of paper can hold 2 pages. Over 12 weeks, how many reams of paper does he need to buy if a ream contains 500 sheets? He writes 3*50=<<3*50=150>>150 pages a week That means he writes 150*52=<<150*52=7800>>7800 pages of short stories a year So he writes 7800+1200=<<7800+1200=9000>>9000 pages a year So he needs 9000/2=<<9000/2=4500>>4500 sheets of paper That means he needs 4500/500=<<4500/500=9>>9 reams of paper #### 3 Eden, Mary and Iris gather sand to fill their sandbox. Eden carried 4 buckets of sand. Mary carried 3 more buckets of sand than Eden. Iris carried 1 less bucket of sand than Mary. If each bucket contains 2 pounds of sand, how many pounds of sand did they collect in total? Mary carried 4 + 3 = <<4+3=7>>7 buckets of sand. Iris carried 7 – 1 = <<7-1=6>>6 buckets of sand. All together, they carried 4 + 7 + 6 = <<4+7+6=17>>17 buckets of sand. The sand weighed a total of 17 * 2 = <<17*2=34>>34 pounds. #### 34 Karen has 32 quarters in her piggy bank. Her older brother Christopher has 64 quarters in his piggy bank. How much more money does Christopher have? Christopher has 64 quarters so he has 64*.25 = $<<64*.25=16.00>>16.00 Karen has 32 quarters so she has 32*.25 = $<<32*.25=8.00>>8.00 If Christopher has $16.00 and Karen has $8.00 then Christopher has 16-8 = $<<16-8=8.00>>8.00 more than Karen #### 8 James hurt himself exercising. The pain subsided after 3 days, but he knew that the injury would take at least 5 times that long to fully heal. After that, he wanted to wait another 3 days before he started working out again. If he wants to wait 3 weeks after that to start lifting heavy again, how long until he can lift heavy again? The injury would be fully healed after 3*5=<<3*5=15>>15 days So he would start exercising again in 15+3=<<15+3=18>>18 days He would then wait for 3*7=<<3*7=21>>21 more days to start lifting heavy again That means he needs to wait 18+21=<<18+21=39>>39 days #### 39
