Q: In a shipping container, there are 10 crates. Each crate is filled with 6 boxes and each box is filled with 4 washing machines. A worker removes 1 washing machine from each box. There are no other changes. How many washing machines were removed from the shipping container?
A: Initially, there were 6 boxes * 4 washing machines per box = 24 washing machines in each crate. So there were 24 washing machines per crate * 10 crates = 240 washing machines in the shipping container. A worker removes 1 washing machine from each box so there are now 4 original washing machines - 1 removed washing machine = 3 washing machines in each box. This means there are 6 boxes * 3 washing machines per box = 18 washing machines in each crate. So there are now 18 washing machines per crate * 10 crates = 180 washing machines in the shipping container. The difference is how many machine washing machines were removed which is 240 initial washing machines 180 current washing machines = 60 washing machines. The answer is 60.
Question: At a party, there are 400 students, a combination of poets, singers and tree huggers. There are 50 more poets than treehuggers at the party. If the number of tree huggers is 120, how many singers are at the party?
Answer: Since there are 50 more poets than treehuggers at the party, the number of poets is 120 + 50 = 170. The number of poets and tree huggers at the party is 170 + 120 = 290. Since the number of attendees at the party also included singers, there are 400 - 290 = 110 singers. The answer is 110.
[Question]Marlon has a gift card for $200. He spent half of it on Monday and one-fourth of the remainder on Tuesday. How much was left on his gift card?
[Answer]Since Marlon spent half of the gift card, then half of it which is $200 / 2 = $100 remained on Monday. Then on Tuesday, he spent $100 / 4 = $25. Therefore, he has $100 - $25 = $75 left in his gift card. The answer is 75.
Q: Hannah wants to save $80 for five weeks. In the first week, she saved $4 and she plans to save twice as much as her savings as the previous week. How much will she save in the fifth week to reach her goal?
A: In the second week, Hannah will save $4 x 2 = $8. In the third week, she will save $8 x 2 = $16. In the fourth week, she will save $16 x 2 = $32. Her total savings for a month will be $4 + $8 + $16 + $32 = $60. Hannah needs to save $80 - $60 = $20 in the fifth week. The answer is 20.
Question: Terry's mom brought home 4 different colored dogs from the shelter. The brown dog weighs 4 pounds. The black dog weighs 1 pound more than the brown dog. The white dog weighs twice as much as the brown dog. The grey dog weighs 2 pounds less than the black dog. What's the average weight of all the dogs?
Answer: Since the black dog weighs 1 pound more than the brown dog, the black dog weighs 1 + 4 = 5 pounds. The white dog weighs 4 * 2 = 8 pounds. Because the grey dog weighs 2 pounds less than the black dog, the grey dog weighs 5 - 2 = 3 pounds. The total weight of all dogs is 4 + 5 + 8 + 3 = 20 pounds. The average weight of all the dogs is 20 / 4 = 5 pounds. The answer is 5.
