Mara and Riley went to a carnival, Mara rode the bumper car two times, Riley rode the space shuttle four times, and they both rode the Ferris wheel three times. If a ticket for a bumper car cost $2, a ticket for a space shuttle cost $4, and a ticket for a Ferris wheel cost $5, how much money did they spend?

How much did Mara spend on the bumper car? ** Mara spent $2 x 2 = $

<<2*2=4>>4 for riding the bumper car two times. How much did Riley spend on the space shuttle? ** Riley spent $4 x 4 = $<<4*4=16>>16 for riding the space shuttle 4 times. How much did they spend on the Ferris wheel? ** They spent $5 x 3 = $<<5*3=15>>15 each riding the Ferris wheel 3 times. How much did they spend on the Ferris wheel? ** So, they spent a total of $15 x 2= $<<15*2=30>>30 riding the Ferris wheel. How much did they spend at the carnival? ** Therefore the total amount they spent at the carnival is $4 + $16 + $30 = $<<4+16+30=50>>50. #### 50 James buys $3000 worth of stuff from Amazon. He has to return a TV that cost $700 and a bike that cost $500. He also sells another bike that cost 20% more than the bike he returned for 80% of what he bought it for. He then buys a toaster for $100. How much is he out of pocket for everything? How much did the TV and bike cost? ** The items he returned were valued at $700 + $500 = $<<700+500=1200>>1200 How much is James out of pocket? ** So far he is out 3000-1200 = <<3000-1200=1800>>1800 after recouping 1200. How much did the other bike cost? ** An item that is 20% more expensive cost 1 + .2 = 1.2 times as much as the item How much did the other bike cost? ** So that means the bike he sold cost $500 * 1.2 = $<<500*1.2=600>>600 How much did he sell the other bike for? ** He sold it for $600 * .8 = $<<600*.8=480>>480 How much was he out of pocket from the other bike? ** From the bike that he had bought for 600, he was out 600-480 =<<600-480=120>>120 How much is James out of pocket for everything? ** So far he is out 1800+120 = <<1800+120=1920>>1920 How much is James out of pocket for everything? ** If he also bought a toaster worth 100, he was out 1920+100 = <<1920+100=2020>>2020 #### 2020 The flowers cost $9, the clay pot costs $20 more than the flower, and the bag of soil costs $2 less than the flower. How much does it cost to plant the flowers? How much does the clay pot cost? ** The clay pot costs $20 + $9 = $<<20+9=29>>29. How much does the bag of soil cost? ** The bag of soil costs $9 - $2 = $<<9-2=7>>7. How much does it cost to plant the flowers? ** The cost to plant the flowers is $9 + $29 + $7 = $<<9+29+7=45>>45. #### 45 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? How many pages could Tom read in one hour if he could triple his reading speed? ** If Tom could triple his reading speed, he could read 12 * 3 = <<12*3=36>>36 pages of a book in one hour. How many pages could Tom read in two hours if he could triple his reading speed? ** 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? How much does The Life Journey cost? ** The total cost of The Life Journey is 3 × $100 = $<<3*100=300>>300. How much does When You Rescind cost? ** The total cost of When You Rescind is 3 × $85 = $<<3*85=255>>255. How much does A Day a Life cost? ** The total cost of A Day a Life is 3 × $50 = $<<3*50=150>>150. How much did I spend in the shop? ** 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? How many dresses can she make? ** 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. How many hours does she have to work? ** 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? How many snakes are there? ** The zoo has 8 x 3 = <<8*3=24>>24 snakes. How many monkeys are there? ** It has 24 x 2 = <<24*2=48>>48 monkeys. How many parrots and snakes are there? ** The number of parrots and snakes added up is 8 + 24 = <<8+24=32>>32 How many elephants are there? ** There are 32/2 = <<32/2=16>>16 elephants. How many zebras are there? ** There are 16 - 3 = <<16-3=13>>13 zebras. What is the difference in number between the zebras and the monkeys? ** 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? How much does Jessica's pumpkin weigh? ** Jessica's pumpkin weighs half the weight of Brad's 54-pound pumpkin so 54/2 = <<54/2=27>>27 pounds How much does Betty's pumpkin weigh? ** Betty's pumpkin weighs 4 times the amount of Jessica's 27-pound pumpkin so it weighs 4*27 = <<4*27=108>>108 What is the difference between the heaviest and lightest pumpkin in pounds? ** 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? How many people were served coffee in the restaurant? ** The number of customers who were served coffee in the restaurant is 3/5*25 = <<3/5*25=15>>15 How many people did not buy coffee in the restaurant? ** 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.

Over 12 weeks, how many reams of paper does he need to buy if a ream contains 500 sheets? How many pages does John write in a week? ** He writes 3*50=<<3*50=150>>150 pages a week How many pages does John write in a year? ** That means he writes 150*52=<<150*52=7800>>7800 pages of short stories a year How many pages does John write in a year? ** So he writes 7800+1200=<<7800+1200=9000>>9000 pages a year How many sheets of paper does John need? ** So he needs 9000/2=<<9000/2=4500>>4500 sheets of paper How many reams of paper does John need? ** That means he needs 4500/500=<<4500/500=9>>9 reams of paper #### 3
