Josh has soccer practice on Monday, Wednesday, and Friday from 3:00 p.m. to 5:00 p.m. He has band practice on Tuesday and Thursday from 3:30 p.m. to 5:00 p.m. From Monday to Friday, how many hours does Josh spend on extracurricular activities?
Let's think: Josh practices soccer 2 hours x 3 days = 6 hours. He practices band 1.5 hours x 2 days = 3 hours. From Monday to Friday, on extracurricular activities, Josh spends 6 + 3 = 9 hours.. The answer is: 9.

Cassie is an athletic person and tries to drink at least 12 cups of water a day to stay hydrated while being active. Her water bottle holds 16 ounces. There are 8 ounces of water in a cup. How many times does Cassie have to refill her water bottle a day to make sure she drinks 12 cups?
Let's think: Cassie needs to drink 8 * 12 = 96 ounces of water to drink 12 cups a day. Thus, Cassie needs to refill her water bottle 96 / 16 = 6 times a day.. The answer is: 6.

Edmund is buying a new computer and needs to save up $75 before he has enough. He convinces his parents to pay him for extra chores. He normally has to do 12 chores a week. His parents agree to pay him $2 for every extra chore he does during the week. If he does 4 chores a day for two weeks, how much does he earn?
Let's think: In two weeks, he has to do 24 chores because 2 x 12 = 24. He now does 28 chores a week because 7 x 4 = 28. He does 56 chores in two weeks because 2 x 28 = 56. He has done 32 extra chores because 56 - 24 = 32. He earns $64 because 2 x 32 = 64.. The answer is: 64.

Jason is counting the number of cars that drive by his window. He counted four times as many green cars as red cars, and 6 more red cars than purple cars. If he counted 312 cars total, how many of them were purple?
Let's think:
Let g be the number of green cars, r be the number of red cars, and p be the number of purple cars. We know that g + r + p = 315, r = p + 6, and g = 4r. Substitute the second equation into the third equation to get: g = 4r = 4(p + 6) = 4p + 24. Now substitute the equations that express g and r in terms of p in the equation for the total number of cars: 4p + 24 + p + 6 + p = 315. Now combine like terms to get 6p + 30 = 312. Now subtract 30 from both sides to get 6p = 282. Now divide both sides by 6 to get p = 47.. The answer is: 47.
