[Question]Cape May and Daytona Beach have 40 shark sightings a year. If Cape May has 8 less than double the number of shark sightings of Daytona Beach, how many shark sightings does Cape May have?
[Answer]Let x be the number of sharks in Daytona Beach. Cape May has 2x - 8 shark sightings. x + (2x - 8) = 40. 3x - 8 = 40. 3x = 48. x = 16. Cape May has 2(16) - 8 = 24 shark sightings. The answer is 24.
Q: Tomas is hoping to run a marathon next year, which is 26.3 miles. He knows that each month he trains, he can run twice as far as the month before. If he can run 3 miles during the first month of training, how many total months before the marathon should he start training to ensure he can run far enough?
A: In the first month he can run 3 miles. In the second month he can run 6 miles because 3 x 2 = 6. In the third month he can run 12 miles because 6 x 2 = 12. In fourth month he can run 24 miles because 12 x 2 = 24. In fifth month he can run 48 miles because 24 x 2 = 48. He needs to start training 5 months ahead of time because 24 < 26.3 and 48>26.3. The answer is 5.
Question: A building has 20 floors. Each floor is 3 meters high, except for the last two floors. The last two floors are each 0.5 meters higher. How tall is the building?
Answer: There are 20 - 2 = 18 floors that are each 3 meters high. So the first 18 floors is 18 x 3 = 54 meters high. The last two floors are each 3 + 0.5 = 3.5 meters high. So the total height of the last two floors is 3.5 x 2 = 7 meters. Therefore, the building is 54 + 7 = 61 meters high. The answer is 61.
[Question]James decides to sell 80% of his toys. He bought them for $20 each and sells them for $30 each. If he had 200 toys how much more money did he have compared to before he bought them?
[Answer]He bought all the toys for 20 * 200 = $4000. He sold 200 * .8 = 160 toys. He made 160 * 30 = $4800 from selling them. So he profits 4800 - 4000 = $800 profit. The answer is 800.
[Question]Harper drinks a 1/2 bottle of mineral water per day. She buys the mineral water by the case at a big box store. They come 24 bottles to a case and are currently on sale for $12.00. If she wants to buy enough cases to last her 240 days, how much will she spend?
[Answer]
She drinks 1 / 2 bottle a day and there are 24 bottles in a case so a case will last 24 / .5 = 48 days. She needs enough to last her 240 days and 1 case will last her 48 days so she needs 240 / 48 = 5 cases. Each case is on sale for $12.00 and she needs 5 cases so that's 12 * 5 = $60.00. The answer is 60.
