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?

Question: Yanni has $0.85. His mother gave him $0.40 in addition. While going to the mall, Yanni found $0.50. He bought a toy that cost $1.6. How much money in cents did Yanni have left?
Answer: Yanni's mother gave him $0.40 in addition to $0.85 for a total of $0.40 + $0.85 = $1.25. Yanni found $0.50 so he had a total of $1.25 + $0.50 = $1.75. Therefore, Yanni had $1.75 - $1.6 = $0.15 left. 100 cents make $1 so $0.15 is 100 * 0.15 = 15 cents. The answer is 15.
Q: Mary's sheep can run 12 feet per second, and her sheepdog can run 20 feet per second. A sheep standing 160 feet away from the sheep dog bolts, and the dog runs after it. How many seconds does it take the dog to catch the sheep?
A:
First find how much faster the dog is than the sheep: 20 feet / second - 12 feet / second = 8 feet / second. Then divide the distance the dog needs to run by the speed difference: 160 feet / 8 feet / second = 20 seconds. The answer is 20.
