Mariel is a dog walker. While walking her pack of dogs, she gets tangled up in the leashes of another dog walker and their 3 dogs. There are 36 legs tangled up in leashes. How many dogs is Mariel walking?

How many legs do the other dog walkers have? ** There are 2 dog walkers and they each have 2 legs so that's 2*2 =

<<2*2=4>>4 legs How many legs do the other dog walkers' dogs have? ** The other dog walker is walking 3 dogs that each have 4 legs so that's 3*4 = <<3*4=12>>12 legs How many legs are tangled up in leashes? ** The dog walkers have 4 legs and the other dogs have 12 legs for a total of 4+12 = <<4+12=16>>16 legs How many legs are tangled up in leakes? ** There are 36 legs total and 16 belong to the dog walkers and 3 dogs so that leaves 36-16 = <<36-16=20>>20 legs How many dogs is Mariel walking? ** Dogs have 4 legs and there are 20 legs so Mariel is walking 20/4 = 5 dogs #### 5 A boat carrying 20 sheep, 10 cows and 14 dogs capsized. 3 of the sheep drowned. Twice as many cows drowned as did sheep. All of the dogs made it to shore. How many total animals made it to the shore? How many sheep made it to shore? ** The boat had 20 - 3 = <<20-3=17>>17 sheep make it to shore. How many cows drowned? ** 3 sheep drowned, so 2 * 3 = <<2*3=6>>6 cows drowned. How many cows made it to shore? ** 10 cows on the boat - 6 drowned = <<10-6=4>>4 cows made it to the shore. How many total animals made it to the shore? ** 17 sheep + 4 cows + 14 dogs = <<17+4+14=35>>35 animals made it to shore. #### 35 The Rotary Club is holding its annual fundraising Omelet Breakfast, with tickets sold in advance. The tickets come in different price levels, for young children, older children, adults, and seniors. This year they sold 53 small children tickets, 35 older children tickets, 75 adult tickets, and 37 senior tickets. To figure out how many eggs they need to buy, the club estimates that small children can eat a half omelet, older children can eat a whole omelet, adults will eat two omelets, and seniors will eat one and a half omelets. Just to be on the safe side, they get enough eggs to make 25 extra omelets. If they use 2 eggs for each omelet, how many eggs will they need to buy? How many omelets will small children eat? ** They'll need to make an estimated 0.5 * 53 = <<0.5*53=26.5>>26.5 omelets for small children. How many omelets will older children eat? ** They'll need to make an estimated 1 * 35 = <<1*35=35>>35 omelets for older children. How many omelets will adults eat? ** They'll need to make an estimated 2 * 75 = <<2*75=150>>150 omelets for the adults. How many omelets will seniors eat? ** And they'll need to make an estimated 1.5 * 37 = <<1.5*37=55.5>>55.5 omelets for the seniors. How many omeels will they need to make? ** Along with the 25 extra omelets they'll make as a buffer, they will need enough eggs for 26.5 + 35 + 150 + 55.5 + 25 = <<26.5+35+150+55.5+25=292>>292 omelets. How many eggs will they need to buy? ** So they will need 2 * 292 = <<2*292=584>>584 eggs. #### 584 There are 4 puppies and 3 dogs at a camp. Each dog eats twice as much food as a puppy, but each puppy eats three times as often as a dog. If a dog eats 4 pounds of food three times a day, what would be the total amount of food the dogs and puppies eat in a day? How much food does a dog eat? ** Eating three times a day, a dog eats 3*4=<<3*4=12>>12 pounds of food. How much food do the dogs eat? ** Since there are 3 dogs at the camp, the total amount of food they eat is 3*12=<<3*12=36>>36 pounds of food in a day. How much food does a puppy eat? ** If each dog eats twice as much food as a puppy, a puppy will eat 4/2=<<4/2=2>>2 pounds of food in one meal. How often does a puppy eat? ** Each puppy eats three times as often as a dog, and if a dog eats three times in a day, a puppy will eat 3*3= <<3*3=9>>9 times in a day. How much food does a puppy eat? ** Since a puppy eats 2 pounds of food a day, the total amount of food a puppy will eat in a day is 9*2=<<9*2=18>>18 pounds of food. How much food do the puppies eat? ** Four puppies in the camp eat 18*4=<<18*4=72>>72 pounds of food every day. How much food do the dogs and puppies eat in a day? ** Together, the dogs and the puppies eat 72+36=<<72+36=108>>108 pounds of food in a day. #### 108 Heloise has dogs and cats in the ratio of 10:17, with the total number of pets being 189. If she gives 10 dogs to her friend Janet, how many dogs does she remain with altogether? How many pets does Heloise have in total? ** The total ratio for the number of cats and dogs that Heloise has is 10+17 = <<10+17=27>>27 How many dogs does Heloise give to Janet? ** From the ratios, the fraction representing the number of dogs is 10/27, and this represents 10/27*189 = <<10/27*189=70>>70 dogs. How many dogs does Heloise remain with altogether? ** If Heloise gives 10 of her dogs to Janet, she remains with 70-10 = <<70-10=60>>60 dogs. #### 60 Antonio is preparing a meal of spaghetti and meatballs for his family. His recipe for meatballs calls for 1/8 of a pound of hamburger per meatball. Antonio has 8 family members, including himself. If he uses 4 pounds of hamburger to make meatballs, and each member of the family eats an equal number of meatballs, how many meatballs will Antonio eat? How many meatballs will Antonio make? ** If one meatball is made from 1/8 pound of hamburger meat, then 4 pounds of hamburger meat will make 4/(1/8)=4*8=<<4/(1/8)=32>>32 meatballs. How many meatballs will each family member eat? ** 32 meatballs divided amongst 8 family members is 32/8=<<32/8=4>>4 meatballs per family member. #### 4 Randy has $30. He spent $10 buying his lunch. He spent a quarter of the money he had left on an ice cream cone. What is the amount of money, in dollars, Randy has left? How much money does Randy have left after buying lunch? ** Randy has 30-10=<<30-10=20>>20 dollars left after buying lunch. How much money did Randy spend on the ice cream cone? ** Randy spent 20/4=<<20/4=5>>5 dollars on the ice cream cone. How much money does Randy have left? ** Randy has 20-5=<<20-5=15>>15 dollars left. #### 15 In 5 years, Andy will be twice as old as Rahim is now. Rahim is 6 now. How much older is Andy than Rahim, right now, in years? How old will Andy be in 5 years? ** Andy will be 2*6=<<2*6=12>>12. How old is Andy now? ** Now he is 12-5=<<12-5=7>>7. How much older is Andy than Rahim, right now, in years? ** So Andy is 7-6=<<7-6=1>>1 year older than Rahim. #### 1 In a show, there can be 5 actors at a time. Every actor is in the show for about 15 minutes, and then another 5 actors come in. How many actors can there be on the show in 1 hour? How many sets of actors can there be in 1 hour? ** One hour is 60 minutes, so there can be 60 / 15 = <<60/15=4>>4 different sets of actors. How many actors can there be in 1 hour? ** This means, that during one hour there can be 4 * 5 = <<4*5=20>>20 different actors in the show. #### 20 Kurt's old refrigerator cost $0.85 a day in electricity. He recently bought a new energy-efficient refrigerator that only cost $0.45 a day in electricity. How much money does Kurt save in a 30-day month with his new refrigerator? How much does the old refrigerator cost? ** The old refrigerator costs $0.85 a day so for 30 days it costs .85*30 = $<<0.85*30=25.50>>25.50 How much does the new refrigerator cost? ** The new refrigerator costs $0.45 a day so for 30 days it costs .45*30 =$<<0.45*30=13.50>>13.50 How much money does Kurt save in a 30-day month with his new refrigerator? ** Over 30 days, Kurt saves 25.50-13.50 = $<<25.50-13.50=12.00>>12.00 a month with his new refrigerator #### 12
