[Question]Tameka is selling boxes of crackers for her scout troop. On Friday, she sold 40 boxes. On Saturday, she sold 10 fewer than twice that number. And on Sunday, she sold half as many as Sunday. How many boxes did she sell over the three days?
[Answer]Saturday's total was 2 * 40 - 10 = 70. Sunday's was 70 / 2 = 35. The sum is 40 + 70 + 35 = 145. The answer is 145.

[Question]In one of the building blocks at Oakland High there are 5 classes. Each class uses 2 whiteboards each and each whiteboard needs about 20ml of ink for a day's use. If ink costs 50 cents per ml, how much (in dollars) would it cost to use the boards for one day?
[Answer]Each ml of ink costs 50 cents so 20 ml costs 20 * 50 = 1000 cents. There are 2 whiteboards in each class so each class needs 2 * 1000 cents = 2000 cents. There are five classes in the block so they all need 5 * 1 * 2000 cents = 10000 cents. 100 cents make a dollar so 10000 cents make 10000 / 100 = $100. The answer is 100.

[Question]Cynthia has three children whose ages add up to 35. Matthew is two years older than Rebecca and four years younger than Freddy. How many years old is Freddy?
[Answer]Let A be Matthew’s age. Rebecca is A - 2 years old. Freddy is A + 4 years old. Their ages add up to 35, so A + A - 2 + A + 4 = 3A + 2 = 35. Therefore, 3A = 35 - 2 = 33. Matthew is A = 33 / 3 = 11 years old. Thus, Freddy is 11 + 4 = 15 years old. The answer is 15.

Since Drew got 20 questions right and 6 wrong, she was asked 20 + 6 = 26 questions. Carla got twice as many questions wrong as Drew got, a total of 2 * 6 = 12 questions wrong. The total number of questions that Carla was asked is 12 + 14 = 26. Altogether, there were 26 + 26 = 52 questions that were asked in the contest. The answer is 52.
