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.
[Question]Jennie drives to her son’s house in 5 hours when there is heavy traffic. When there is no traffic the same trip takes only 4 hours. If her son's house is 200 miles away, what is the difference between her average speed when there is heavy traffic and when there is no traffic?
[Answer]Jennie can cover the 200 - mile distance in 5 hours when there is heavy traffic, so her average speed is 200 / 5 = 40mph. She can cover the same distance in 4 hours when there is no traffic for an average speed of 200 / 4 = 50mph. The difference in average speed between the two scenarios is (50 - 40)mph = 10mph. The answer is 10.

Question: Annie plants 3 pots of basil, 9 pots of rosemary, and 6 pots of thyme. Each basil plant has 4 leaves, each rosemary plant has 18 leaves, and each thyme plant has 30 leaves. How many leaves are there total?
Answer:
First find the total number of basil leaves: 3 pots * 4 leaves / pot = 12 leaves. Then find the total number of rosemary leaves: 9 pots * 18 leaves / pot = 162 leaves. Then find the total number of thyme leaves: 6 pots * 30 leaves / pot = 180 leaves. Then add the number of each type of leaf to find the total number of leaves: 12 leaves + 162 leaves + 180 leaves = 354 leaves. The answer is 354.
