Hannah brought $30 to the county fair. She spent half of it on rides and another $5 on dessert. How much, in dollars, is left?
Let's think: She spent $30 / 2 = $15 on rides. She spent a total of $15 + $5 = $20 including dessert. She has $30 - $20 = $10 left.. The answer is: 10.

It's February 2021. Mark was born in January 1976. Graham is 3 years younger than Mark, and Graham's sister, Janice, is 1/2 the age of Graham. How old is Janice?
Let's think: It's 2021 and Mark was born in 1976 so Mark is 2021 - 1976 = 45 years old. Graham is 3 years younger than Mark who is 45 so Graham is 45 - 3 = 42 years old. Janice is 1 / 2 the age of Graham who is 42 so Janice is 42 / 2 = 21 years old.. The answer is: 21.

Mark wants to have a water balloon fight with his friends. He goes to the store to buy balloons and sees that they sell small bags for $4, medium bags for $6 and extra large bags for $12. He has $24 and wants to get the most balloons as possible. If the $4 bags contain 50 balloons, the $6 bags contain 75 balloons and the $12 bags contain 200 balloons, what is the greatest number of balloons he can buy?
Let's think: He can buy 6 small bags because 24 / 4 = 6. These give him 300 balloons, because 6 x 50 = 300. He can buy 4 medium bags because 24 / 6 = 4. These give him 300 balloons because 4 x 75 = 300. He can buy 2 extra large bags because 24 / 12 = 2. This gives him 400 balloons because 2 x 200 = 400. 400 is the most he can buy because 400 is greater than 300.. The answer is: 400.

Maisie and Donna dropped off flyers for a neighborhood clean-up day at houses around their neighborhood. Maisie walked down the shorter left street and dropped off 33 flyers. Donna took the long right street on her bicycle and dropped off five more than twice as many flyers as Maisie. How many flyers did Donna drop off?
Let's think:
Twice as many flyers as Maisie is 33 * 2 = 66 flyers. Donna dropped off five more than that, so she dropped off 66 + 5 = 71 flyers.. The answer is: 71.
