Q: On a construction site, the Laker cement factory provided 500 bags of cement sold to Mr. Zander at $10 per bag. Mr. Zander also received twenty lorries of construction sand, each carrying 10 tons of sand, sold at $40 per ton. How much money did Mr. Zander pay for these construction materials?
A: 13000
Step-by-step reasoning process: The total cost for the sand is 500 * 10 = $5000. Since each lorry was carrying 10 tons of sand, the twenty lorries carried 20 * 10 = 200 tons. At $40 per ton, Mr. Zander paid 200 * $40 = $8000 for the sand that was delivered to his construction site. Altogether, Mr. Zander paid $8000 + $5000 = $13000 for the delivered construction materials.

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: 60
Step-by-step reasoning process: 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.

Q: Katya sold 8 glasses of lemonade and Ricky sold 9 glasses of lemonade. If Tina sold twice as many as Katya and Ricky's combined sales, how many more glasses of lemonade than Katya did Tina sell?
A: 26
Step-by-step reasoning process: Katya and Ricky sold 8 + 9 = 17 glasses of lemonade. Tina sold 17 x 2 = 34 glasses of lemonade. Tina sold 34 - 8 = 26 more glasses of lemonade than Katya.

Q: Megan went to the store and bought a dozen eggs. When she got home, her neighbor gave her another dozen eggs from her chickens. Megan used 2 eggs to make an omelet for dinner and 4 eggs to bake a cake. When Megan's aunt came over for a visit, Megan gave her half of her remaining eggs. How many eggs per meal would Megan have if she plans to divide what she has left equally for her next 3 meals?
A: 3
Step-by-step reasoning process: Megan has 12 + 12 = 24 eggs. After making her omelet and cake, she was left with 24 - 2 - 4 = 18 eggs. After giving half to her aunt, she was left with 18 / 2 = 9. Megan would have 9 / 3 = 3 eggs per meal for the next three meals.
