Q: There are 24 toys in the box and ¼ of them are action figures. The remaining toys are all dolls. How many dolls are there?
A: Since there are 24 toys in the box, there are ¼ * 24 = 6 action figures. Because the rest of the toys are dolls, there are 24 - 6 = 18 dolls in the box. The answer is 18.

Q: Nellie can eat 12 sourball candies before crying. Jacob can only manage half of that number of candies, and Lana can only do three fewer than Jacob. They had a bucket of 30 candies, and all of them ate until they cried. If they divide the remaining candies in the bucket equally, how many sourball candies will they each get?
A: Jacob can eat 12 / 2 = 6 candies before crying. Lana can eat 6 - 3 = 3 candies before crying. Nellie, Jacob, and Lana all ate until they cried, so they ate 12 + 6 + 3 = 21 candies. Thus, there are 30 - 21 = 9 candies left in the bucket. After dividing the remaining candies equally, they will each get 9 / 3 = 3 sourball candies. The answer is 3.

Let’s use p for the number of feet in Mark’s pond. 3 * p + 4 = 19. 3 * p = 19 - 4 = 15. 3p = 15. p = 5. The answer is 5.
