Answer the following question.
Nina wants to buy a new video game with her allowance money. The game cost 50 dollars. Nina also has learned that there is a 10 percent sales tax. She receives 10 dollars a week as an allowance, and thinks she can save half of that. How many weeks will it take for Nina to be able to buy the new video game with her savings?
Step-by-step reasoning process: The 10 percent tax on 50 dollars will be 10 / 100 x 50 = 5 dollars. The cost of the game and the tax will be 50 + 5 = 55 dollars. Nina will save half of her allowance every week, or 10 / 2 = 5 dollars per week. The total cost of the game and tax, divided by Nina's weekly savings is 55 / 5 = 11 weeks.
The answer is 11.

Answer the following question.
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?
Step-by-step reasoning process: 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.
The answer is 72.

Answer the following question.
Codger is a three-footed sloth. He has a challenging time buying shoes because the stores only sell the shoes in pairs. If he already owns the 3-piece set of shoes he is wearing, how many pairs of shoes does he need to buy to have 5 complete 3-piece sets of shoes?
Step-by-step reasoning process: To have five 3 - piece sets, he needs to have a total of 5 * 3 = 15 shoes,. If he already owns three shoes, then he needs to buy 15 - 3 = 12 additional shoes. Since each pair of shoes includes two shoes, he needs to buy a total of 12 / 2 = 6 pairs of shoes.
The answer is 6.
