If Monty was having a family reunion for 36 family members, how much will it cost him to buy enough chicken and sides to feed everyone one serving? How many combos does Monty need? ** Monty needs to feed 36 family members and each chicken/meal combo feeds 6 people so he needs 36/6 = <<36/6=6>>6 combos How much will it cost him to buy enough chicken and sides to feed everyone one serving? ** Each chicken/meal combo costs $12.00 and he needs 6 so it will cost him 12*6 = $<<12*6=72.00>>72.00 to feed everyone #### 72 Mr Fletcher hired 2 men to dig a well in his compound. They worked for 10 hours on the first day, 8 hours on the second day and finished the job on the third day after working 15 hours. If Mr Fletcher paid each of them $10 per hour of work, calculate the total amount of money they received altogether? How many hours did each worker work in the first 2 days? ** The total number of hours each worker works in the first 2 days is 10+8 = <<10+8=18>>18 hours. How many hours did each worker work in total? ** Since they completed the job in three days, each was compensated for 18+15 = <<18+15=33>>33 hours of work. How much money did each worker receive altogether? ** Mr Fletcher paid each of the workers $10 per hour of work, meaning for 33 hours, each of the workers received 33*$10 = $<<10*33=330>>330 How much money did each worker receive altogether? ** Since they were two workers, the total amount they received all together after each was paid $330 is $330*2 = $<<330*2=660>>660 #### 660 Mrs. Anderson bought 2 bags of 3-pound bag of cat food and another 2 bags of dog food that each weigh 2 more pounds than each bag of cat food. There are 16 ounces in each pound. How many ounces of pet food did Mrs. Anderson buy? How many pounds of cat food does Mrs. Anderson buy? ** The two bags of cat food weigh 2 x 3 = <<2*3=6>>6 pounds. How many pounds of dog food does Mrs. Anderson buy? ** Each bag of dog food weighs 3 + 2 = <<3+2=5>>5 pounds. How many pounds of dog food does Mrs. Anderson buy? ** So two bags of dog food weigh 2 x 5 = <<2*5=10>>10 pounds. How many pounds of pet food did Mrs. Anderson buy? ** Thus, Mrs. Anderson bought 6 + 10 = <<6+10=16>>16 pounds of pet food. How many ounces of pet food did Mrs. Anderson buy? ** And 16 pounds is equal to 16 x 16 = <<16*16=256>>256 ounces. #### 256 A small zoo houses a variety of 68 wild animals. After they send a gorilla family of six to a different zoo, they adopt a hippopotamus from another zoo. A while later, an animal rescue contacted them, and the zoo took in three endangered rhinos. Then one of their lionesses gave birth to cubs, and they opened a meerkat exhibit with twice as many meerkats as they had gained lion cubs. The zoo then had 90 animals in all. How many lion cubs were born at the zoo? Define a variable ** Let C be the number of lion cubs. How many meerkats are in the new exhibit? ** There are 2C meerkats in the new exhibit. How many animals were left after the gorillas were sent away? ** The zoo sent 4 gorillas away, so they had 68 - 6 = <<68-6=62>>62 animals left. How many animals were left after the hippo was adopted? ** They adopted a hippopotamus, so they had 62 + 1 = <<62+1=63>>63 animals. How many animals were left after the rhinos were taken in? ** They took in 3 rhinos, so they had 63 + 3 = <<63+3=66>>66 animals. How many new lion cubs and meerkats were born at the zoo? ** Thus, they had 90 - 66 = <<90-66=24>>24 new lion cubs and meerkats. How many new lion cubs were born at the zoo? ** Therefore, they had C + 2C = 3C = 24 new lion cubs as meerkats. How many lion cubs were born at the zoo? ** Hence, there were C = 24 / 3 = <<24/3=8>>8 lion cubs born. #### 8 Grace is looking to plant some lettuce in her raised bed garden. Her raised bed is comprised of 2 large beds on top with 2 medium beds on the bottom. The top bed can hold 4 rows of lettuce with 25 seeds being sown per row. The medium bed can house 3 rows with 20 seeds being sown per row. How many seeds can Grace plant in all four beds of her raised bed garden? How many seeds can a large bed hold? ** A large bed can hold 4 rows with 25 seeds per row, 4 * 25=<<4*25=100>>100 seeds per large bed How many seeds are needed in total? ** 100 seeds per large bed and there are 2 beds, 100 * 2= <<100*2=200>>200 seeds needed in total for both large beds. How many seeds can a medium bed hold? ** A medium bed can hold 3 rows with 20 seeds sown per row, 3 * 20=<<3*20=60>>60 seeds per medium bed. How many seeds are needed in total? ** 60 seeds per medium bed and there are 2 medium beds, 60 * 2=<<60*2=120>>120 seeds needed in total for both medium beds. How many seeds can Grace plant in all four beds of her raised bed garden? ** 200 seeds needed for the large beds combined with 120 seeds needed for the medium beds comes to 200 +120= <<200+120=320>>320 seeds needed to plant all four beds of the raised garden bed. #### 320 To make 3 liters of ketchup Ashley needs 69 kg of tomatoes. How many kilos of tomatoes does Ashley need to make 5 liters of ketchup?
