If it takes 8 days for 3 builders to build a cottage. How long will it take 6 builders to build the same size cottage working at the same rate?

It would take one builder 8 x 3 =

<<8*3=24>>24 days to build the cottage on his own. 6 builders can build the house in 24 / 6 = <<24/6=4>>4 days. #### 4 Berry is curious about what his average temperature is during the week. On Sunday his temperature is 99.1. On Monday his temperature is 98.2. On Tuesday his temperature is 98.7. On Wednesday his temperature is 99.3. On Thursday his temperature is 99.8. On Friday his temperature is 99. On Saturday his temperature is 98.9. What is his average temperature that week? He total temperature for the week is 692 because 99.1 plus 98.2 plus 98.7 plus 99.3 plus 99.8 plus 99 plus 98.9 equals 692. His average temperature is 99 degrees because 693 divided by 7 equals <<693/7=99>>99. #### 99 Kathryn moved to a new city for the new job she had landed two weeks ago. Her rent was $1200, 1/2 of what she spent on food and travel expenses in a month. Luckily, she found a new friend Shelby, who moved in with her to share the rent. If her salary was $5000 per month, how much money remained after her expenses? If the rent is half what she spends on food and travel expenses, she spends 1200*2 = $<<1200*2=2400>>2400 on food and travel costs. When her friend moved in and shared the rent costs with her, she started paying 1/2*1200 = $<<1200/2=600>>600 in rent costs. Her total monthly expenses is now 600+2400 = $<<600+2400=3000>>3000. When she deducts her monthly expenses from her salary, she has $5000-$3000 = $<<5000-3000=2000>>2000 remaining. #### 2000 Mr. Isaac rides his bicycle at the rate of 10 miles per hour for 30 minutes. If he rides for another 15 miles, rests for 30 minutes, and then covers the remaining distance of 20 miles, what's the total time in minutes took to travel the whole journey? If in one hour he covers 10 miles and rides for 15 miles at the rate of 10 miles per hour, then the time taken for the 15 miles will be 15/10 = <<15/10=1.5>>1.5 hours. The time in minutes is 1.5 * 60 = <<1.5*60=90>>90 minutes. The time taken for the remaining 20 miles at a rate of 10 miles per hour is 20/10= <<20/10=2>>2 hours. The time in minutes is 2*60 = <<2*60=120>>120 minutes. The total time taken for the whole journey is the first 30 minutes + 90 + 30 minutes for resting +120 minutes = <<30+90+30+120=270>>270 minutes. #### 270 It takes 50 large jelly beans to fill up a large drinking glass. It takes half that amount to fill up a small drinking glass. If there are 5 large drinking glasses and 3 small ones, how many jellybeans will it take to fill them up? A small drinking glass takes half the amount of a large glass that needs 50 so it will take 50/2 = <<50/2=25>>25 jellybeans 5 large glasses need to be filled so they will take 5*50 = <<5*50=250>>250 jelly beans There are 3 small glasses that need to be filled so they will take 3*25 = <<3*25=75>>75 jelly beans All total, to fill all the glasses it will take 250+75 = <<250+75=325>>325 jellybeans #### 325 A 25 story building has 4 apartments on each floor. If each apartment houses two people, how many people does the building house? If each building floor has 4 apartments, we have 25 floors * 4 apartments/floor = <<25*4=100>>100 apartments. If each apartment has 2 people, 100 apartments * 2 people/apartment = <<100*2=200>>200 people. #### 200 Jose had 400 tabs opened up in his windows browser. After about one hour of browsing, he closed 1/4 of the tabs to allows easy browsing. He read some news from different pages, then closed 2/5 of the remaining tabs. If he closed half of the remaining tabs after further analyzing some pages, how many windows tabs did he have remaining open? When he closed 1/4 of the tabs, he closed 1/4*400 = <<400*1/4=100>>100 tabs. The number of windows tabs that remained open is 400-100 = <<400-100=300>>300 After reading some news from different pages, he closed 2/5 of the remaining tabs, a total of 2/5*300 = <<2/5*300=120>>120 pages. The number of tabs that remained open is 300-120 = <<300-120=180>>180 If he closed half of the remaining tabs after further analyzing some pages, he closed a total of 1/2*180 = <<180/2=90>>90 pages. The total number of tabs that remained opened is 180-90 = <<180-90=90>>90 #### 90 A garden store sells packages of pumpkin seeds for $2.50, tomato seeds for $1.50, and chili pepper seeds for $0.90. Harry is planning to plant three different types of vegetables on his farm. How much will Harry have to spend if he wants to buy three packets of pumpkin seeds, four packets of tomato seeds, and five packets of chili pepper seeds? The cost of three packets of pumpkin seeds is 3 x $2.50 = $<<3*2.5=7.50>>7.50. The cost of four packets of tomato seeds is 4 x $1.50 = $<<4*1.5=6>>6. And, the cost of five packets of chili pepper seeds is 5 x $0.90 = $4.50. Therefore, Harry will spend $7.50 + $6 + $4.50 = $<<7.5+6+4.5=18>>18. #### 18 Tom catches crabs for a living. He has 8 crab buckets that he checks every day. Each crab bucket gets 12 crabs. He sells each of these crabs for $5 each. How much money does he make per week? He catches 8*12=<<8*12=96>>96 crabs a day So he makes 96*5=$<<96*5=480>>480 per day That means he makes 7*480=$<<7*480=3360>>3360 a day #### 3360 In the park, the first rose bush has 12 red flowers. The second rose bush has 18 pink flowers. The third rose bush has 20 yellow flowers. The fourth rose bush has 8 orange flowers. For her vase, Lorelei picks 50% of the red roses, 50% pink roses, 25% of the yellow roses, and 25% orange roses. How many roses are in her vase? The number of red roses Lorelei picks is 12 x 50% = <<12*50*.01=6>>6 roses. The number of pink roses Lorelei picks is 18 x 50% = <<18*50*.01=9>>9 roses. The number of yellow roses she picks is 20 x 25% = <<20*25*.01=5>>5 roses. The number of orange roses she picks is 8 x 25% = <<8*25*.01=2>>2 roses. The total number of roses in her vase is 6 + 9 + 5 + 2 = <<6+9+5+2=22>>22 roses. #### 22
