Reasoning and answer: 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: 60

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: 20
Reverse engineering the question: 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?


Reasoning and answer: Each son receives 300 / 3 = 100 pieces. Rhys places 25 x 2 = 50 pieces. Rory places 25 x 3 = 75 pieces. All three boys place 25 + 50 + 75 = 150 pieces. The boys have not placed 300 - 150 = 150 pieces.
The answer: 150
