Blake wants to spend his Friday making milkshakes for his family. He knows that he needs 4 ounces of milk and 12 ounces of ice cream for each milkshake. If he has 72 ounces of milk and 192 ounces of ice cream, how much milk will be left over when he is done?

He has enough milk to make 18 milkshakes because 72 / 4 =

<<72/4=18>>18 He has enough ice cream to make 16 milkshakes because 192 / 12 = <<192/12=16>>16 He can only make 16 milkshakes because 16 < 18 He will use 64 ounces of milk because 16 x 4 = <<16*4=64>>64 He will have 8 ounces of milk left because 72 - 64 = <<72-64=8>>8 #### 8 A cargo ship moving from Shanghai to Vancouver navigates for 21 days before reaching port. Customs and regulatory processes in Vancouver last 4 days. Finally, moving the cargo from the port to your rural warehouse takes some time and it always arrives on the seventh day. How many days ago should the ship have departed if your warehouse is expecting the shipment 2 days from today? The total lead time for the cargo is 21 days on water + 4 in customs + 7 to the warehouse or 21+4+7 = <<21+4+7=32>>32 days If the warehouse is expecting the cargo in 2 days from today then the cargo should have already completed 32 - 2 = <<32-2=30>>30 days of lead time #### 30 A big box store sees 175 people enter their store every hour. This number doubles during the holiday season. During the holiday season, how many customers will this big box store see in 8 hours? They see 175 people per hour and this number doubles during the holiday season so that's 175*2 = <<175*2=350>>350 people per hour In an 8 hour day, if 350 people visit every hour then they will see 8*350 = <<350*8=2800>>2,800 people in 8 hours #### 2800 A notebook costs three times as much as a pen. If a pen costs $1.50, how much will Lyle pay for 4 notebooks? A notebook costs $1.50 x 3 = $<<1.5*3=4.50>>4.50. So Lyle will pay $4.50 x 4 = $<<4*4.5=18>>18 for the 4 notebooks. #### 18 Daniel has 5 jars of juice containing 2 liters each. He wants to serve a full glass of juice to each person at a party. He knows that each glass can hold up to 250 milliliters of juice. How many full glasses can he give? The total liters of juice he has is 5 jars x 2 liters/jar = <<5*2=10>>10 liters of juice Then he needs to convert this amount to milliliters: 10 liters x 1000 milliliters/liter = <<10000=10000>>10,000 milliliters He can fill up to 10,000 ml / 250 ml/glass = <<10000/250=40>>40 glasses #### 40 Karen hangs 6 ferns around her house. Each fern has 7 fronds, and each frond has 30 leaves. How many leaves do all the ferns have? First find the total number of fronds on all the ferns: 7 fronds/fern * 6 ferns = <<7*6=42>>42 fronds Then find the total number of leaves on 42 fronds: 42 fronds * 30 leaves/frond = <<42*30=1260>>1260 leaves #### 1260 Bill started reading a book on the first day of April. He read 8 pages every day and by the 12th of April, he had covered two-thirds of the book. How many pages does the book have? He read 8 pages every day for 12 days for a total of 8*12 = <<8*12=96>>96 pages 96 pages is the same as two-thirds of the total number of pages which means: number of pages*(2/3) = 96 Therefore the total number of pages is 96*(3/2) = <<96*(3/2)=144>>144 pages #### 144 Karen is a dog groomer. Rottweilers take 20 minutes to groom, border collies take 10 minutes to groom, and chihuahuas take 45 minutes to groom because they ferociously resist. How many minutes will it take Karen to groom 6 Rottweilers, 9 border collies and 1 chihuahua? First find the total time Karen spending grooming Rottweilers: 20 minutes/Rottweiler * 6 Rottweilers = <<20*6=120>>120 minutes Then find the total time she spends grooming border collies: 10 minutes/border collie * 9 border collies = <<10*9=90>>90 minutes Then add the time spent grooming all three kinds of dogs to find her total grooming time: 120 minutes + 90 minutes + 45 minutes = <<120+90+45=255>>255 minutes #### 255 Jill runs a business breeding llamas. Nine of her llamas got pregnant with 1 calf, and 5 of them got pregnant with twins. After they give birth, Jill traded 8 of the calves for 2 new adult llamas. Then she sells 1/3 of her herd at the market. How many total llamas (calves and adults) does Jill have now? The number of calves that will be born as twins is 5 * 2 = <<5*2=10>>10 calves. The total number of adults and calves before the trade is 9 + 5 + 9 + 10 = <<9+5+9+10=33>>33. Jill had 33 - 8 = <<33-8=25>>25 left for trading 8 of the claves. But, she got 2 adult llamas in return, so she now has a total of 25 + 2 = <<25+2=27>>27 llamas. She then sold 27 / 3 = <<27/3=9>>9 llamas in the market. So, Jill has 27 - 9 = <<27-9=18>>18 llamas now. #### 18 Isabella has three times as many green houses as yellow houses. She also has 40 fewer yellow houses than red houses. If she has 90 green houses, how many of her houses are not yellow? If the number of green houses is three times the number of yellow houses, and there are 90 green houses, then there are 90/3 = 30 yellow houses. She also has 40 fewer yellow houses than blue houses, meaning there are 30+40 = <<30+40=70>>70 blue houses. The number of houses that are not yellow is 70 blue houses +90 green houses = <<70+90=160>>160 #### 160
