Q: 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?
A: 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.
Question: A school bus traveled for 42 minutes at a speed of 50 mph. What is the distance the bus traveled in miles?
Answer: 1 hour = 60 minutes. We convert the time to hours, so 42 minutes = 42 / 60 hours = 7 / 10 hours. So in 42 minutes, the distance the bus traveled in miles is 50 * (7 / 10) = 35 miles. The answer is 35.

Q: Jerry works as an independent contractor for a company that pays him $40 per task. If each task takes him two hours to complete and he works 10 hours a day for a whole week, calculate the total amount of money he would earn at the end of the week.
A: If a task takes two hours to complete and Briar works for ten hours a day, he manages to complete 10 / 2 = five tasks a day. Since each task pays him $40, for the five tasks, he makes $40 * 5 = $200. If he works for a whole week, he makes $200 * 7 = $1400. The answer is 1400.
Question: Ken buys gummy vitamins. They are usually $15.00 per bottle at his grocery store, but they are currently 20% off. On top of that, he has 3 $2.00 coupons. How much will 3 bottles cost?
Answer: The vitamins are $15.00 a bottle and are currently 20% off so that's 15 * .20 = $3.00 off. The vitamins are $15.00 and they are $3.00 off so they are now 15.00 - 3 = $12.00. He has 3 $2.00 coupons so that's 3 * 2 = $6.00 in coupons. He buys 3 bottles at $12.00 each so that's 3 * 12 = $36.00. He has $6.00 in coupons so his vitamins will now costs 36 - 6 = $30.00. The answer is 30.
