There were 90 jellybeans in a jar. Samantha snuck 24 jellybeans out of the jar, without being seen. Shelby ate 12 jellybeans from the jar. Their mom, Shannon, refilled the jar with half as much as Samantha and Shelby took out. How many jellybeans are in the jar now? Give me reasons, before answering the question
There were 90 - 24 = 66 jellybeans in the jar after Samantha snuck some. There were 66 - 12 = 54 jellybean in the jar after Shelby ate some. Samantha and Shelby took 24 + 12 = 36 jellybeans from the jar. Shelby refilled the jar with 36 / 2 = 18 jellybeans. There are 54 + 18 = 72 jellybeans in the jar. So the final answer is 72.
