Question: The United States flag has 50 stars, one for every state in the union, and 13 stripes, which represent the original 13 colonies. Pete, inspired by history, decided to make his own flag. He used circles, to represent how many scoops of ice cream he can consume in one sitting, and squares, to represent the number of brownies he has hidden beneath his bed. For circles, he used 3 less than half the number of stars on the US flag, and for squares, he used six more than twice the number of stripes on the US flag. What is the combined total number of circles and squares on Pete's flag?
Answer: Half the number of stars on the US flag is 50 / 2 = 25. Three less than half the number of stars on the US flag is 25 - 3 = 22 circles. Twice the number of stripes on the US flag is 13 * 2 = 26. Six more than twice the number of stripes on the US flag is 26 + 6 = 32 squares. In total, Pete's flag has 22 + 32 = 54 circles and squares. The answer is 54.
[Question]Tamika drove for 8 hours at an average speed of 45 miles per hour. Logan drove for 5 hours at 55 miles an hour. How many miles farther did Tamika drive?
[Answer]Tamika drove 8 hours * 45 mph = 360 miles. Logan drove 5 hours * 55 mph = 275 miles. 360 - 275 = 85 miles. Tamika drove 85 miles farther. The answer is 85.
Q: From March to August, Sam made $460 doing 23 hours of yard work. However, from September to February, Sam was only able to work for 8 hours. If Sam is saving up to buy a video game console that costs $600 and has already spent $340 to fix his car, how many more hours does he need to work before he can buy the video game console?
A: Sam makes $460 / 23 hrs = $20 / hr. From September to February, Sam made 8hrs x $20 / hr = $160. From March to February, Sam made a total of $460 + $160 = $620. After fixing his car, he was left with $620 - $340 = $280. Sam needs another $600 - $280 = $320. Sam needs to work another $320 / $20 / hr = 16 hours. The answer is 16.
Question: There have been 15 "Where's Waldo?" books published. Each book has 30 puzzles to find Waldo. The average person takes 3 minutes to find Waldo in a puzzle. How long would it take to find every Waldo?

Grayson first travels 1 * 25 = 25 miles. Then Grayson travels 0.5 * 20 = 10 miles. Grayson travels a total of 25 + 10 = 35 miles. Rudy travels 3 * 10 = 30 miles. Grayson travels 35 - 30 = 5 miles more than Rudy. The answer is 5.
