[Question]John is laying the foundation for 3 homes. Each home needs a slab of concrete that is 100 feet by 100 feet by .5 feet. Concrete has a density of 150 pounds per cubic foot. A pound of concrete cost $.02 per pound. How much does the foundation cost?
[Answer]The volume of the slab is 100 * 100 * .5 = 5000 cubic feet. So it weighs 5000 * 150 = 750000 pounds. That means the cost is 750000 * $0.02 = $15,000 per house. So the total cost for all 3 houses is $15000 * 3 = $45,000. The answer is 45000.

[Question]Laran has started a poster business. She is selling 5 posters per day at school. Two posters per day are her large posters that sell for $10. The large posters cost her $5 to make. The remaining posters are small posters that sell for $6. They cost $3 to produce. How much profit, in dollars, does Laran make per 5-day school week?
[Answer]The profit made for each large poster is $10 - $5 = $5. Each day Laran earns $5 * 2 = $10 from selling large posters. The profit made for each small poster is $6 - $3 = $3. Each day Laran earns $3 * 3 = $9 from selling small posters. Laran makes a total profit of $10 + $9 = $19 per day. For a 5 day school week, Laran makes a profit of 5 * $19 = $95. The answer is 95.

[Question]After geometry class, Bill wants to count how many lines he drew. For each shape, he drew one line per side. If he drew 12 triangles, 8 squares, and 4 pentagons, how many lines did he draw?
