A quantity surveyor is figuring the construction costs for a couple that wishes to build a house. The costs are as follows: land costs $50 per square meter, bricks cost $100 per 1000 bricks and roof tiles cost $10 per roof tile. If the house they wish to build requires 2000 square meters, 10000 bricks, and 500 roof tiles, how much construction costs are required for this project? Give the rationale and then the answer.
Let's think step by step. The cost required for buying land is $50 / sq m * 2000 sq m = $100000. The cost required for buying bricks is $100 / 1000 bricks * 10000 bricks = $1000. The cost required for buying roof tiles is $10 / tile * 500 tiles = $5000. The total construction cost is $100000 + $1000 + $5000 = $106000.. The answer is: 106000.

Tara has a shoebox that is 4 inches tall and 6 inches wide. She puts a square block inside that is 4 inches per side. How many square inches of the box are left uncovered? Give the rationale and then the answer.
Let's think step by step. The shoebox is 24 square inches because 4 x 6 = 24. The block is 16 square inches because 4 x 4 = 16. There are 8 square inches uncovered because 24 - 16 = 8.. The answer is: 8.

In a class of 25 students, students were asked if they like French fries, burgers, or neither. 15 students said they like French fries and 10 said they like burgers, with these statistics including the responses of 6 students who said they like both French fries and burgers. How many students do not like either food? Give the rationale and then the answer.
Let's think step by step. There are 15 - 6 = 9 students who like French fries only. There are 10 - 6 = 4 students who like burgers only. So, 9 + 4 + 6 = 19 students like either French fries, burgers, or both. Hence, 25 - 19 = 6 students do not like either fries or burgers.. The answer is: 6.
