[Question]Suzanna's history textbook has 160 pages and her geography textbook has 70 more pages. Her math textbook has half of the sum of the first two books' pages, and her science textbook has twice the number of pages of her history textbook. If Suzanna stacks all her textbooks on her desk, how many pages would there be in total?
[Answer]Her geography textbook has 160 + 70 = 230 pages. The sum of pages of her history and geography textbook is 160 + 230 = 390 pages. Her math textbook has 390 / 2 = 195 pages. Her science textbook has 160 x 2 = 320 pages. In total, there would be 160 + 230 + 195 + 320 = 905 pages. The answer is 905.
Q: Ronnie is a train engineer. His train pulls 3 red boxcars, 4 blue boxcars, and 7 black boxcars. If the black boxcars can each hold 4000 pounds of coal, which is half as much as what the blue boxcars can hold, and the red boxcars can hold 3 times as much as the blue boxcars, how many pounds of coal can all of the train's boxcars combined hold?
A: If we let X represent the number of pounds of coal that the blue boxcar can hold, then 4000 = (1 / 2)X. Solving for X, we get X = 8000 pounds of coal, which represents what the blue car can hold. Thus, the red boxcar can hold 3 * 8000 = 24,000 pounds of coal. 3 red boxcars can carry 3 * 24,000 = 72,000 pounds of coal. 7 black boxcars can carry 7 * 4,000 = 28,000 pounds of coal. 4 blue boxcars carry 4 * 8,000 = 32,000 pounds of coal. Together, all the trains boxcars can carry 72,000 + 28,000 + 32,000 = 132,000 pounds of coal. The answer is 132000.
Question: It's Mother's day, so mothers get a 10% discount on the department store. Mothers who have 3 children or more can get an additional 4% off the discounted price. If Mrs. Brown has 4 children and wants to buy a pair of shoes that costs $125, how much will she pay?
Answer: Mrs. Brown has a $125 x 10 / 100 = $12.5 discount for her purchase. So, the remaining amount she needs to pay is $125 - $12.5 = $112.5. But Mrs. Brown can still avail of the 5% discount, so she has an additional discount of $112.5 x 4 / 100 = $4.5. Therefore, Mrs. brown will only pay $112.5 - $4.5 = $108. The answer is 108.
[Question]A quarterback throws 50 passes in one game. He throws twice as many passes to the right of the field than he does to the left of the field. He throws 2 more passes to the center of the field than he did to the left. How many passes did he throw to the left side of the field?
[Answer]Let x represent the number of passes thrown to the left side of the field. Right:2x. Center:x + 2. Total:x + 2x + x + 2 = 50. 4x + 2 = 50. 4x = 48. x = 12 passes. The answer is 12.
Q: 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?
A: 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.
