Q: Michael has a lot of matchsticks at home and decides to use them to make miniature models. As he is about to start crafting, he has second thoughts and decides to only use half of his pile of matchsticks. He creates 30 matchsticks houses. If he has now used all of the matchsticks he intended to and each matchstick house uses 10 matchsticks, how many matchsticks did Michael have originally?
A: Michael has used a total of 30 matchstick houses * 10 matchsticks per matchstick house = 300 matchsticks. As he only used half of his collection for crafting, he must have originally had 300 matchsticks * 2 = 600 matchsticks. The answer is 600.
Question: Andrew installed hardwood flooring in his house. His bedroom took eight wooden planks, his living room took twenty planks, and his kitchen took eleven planks. The guest bedroom took two fewer planks than Andrew's bedroom, and each of his two hallways took four planks. He accidentally ruined three planks in each bedroom by dragging furniture over them and had to replace them. He ended up with six leftover planks at the end. How many wooden planks did Andrew buy to start with?
Answer: Andrew's guest bedroom took 8 - 2 = 6 wooden planks. His hallways took 2 * 4 = 8 planks. In two bedrooms, he ruined 3 planks each, so the bedrooms took an extra 3 * 2 = 6 planks. In all, he used 8 + 20 + 11 + 6 + 8 + 6 = 59 planks for his whole house. Andrew had 6 leftover planks, so he bought 59 + 6 = 65 wooden planks to start with. The answer is 65.

[Answer]Carla is currently 2 + 2 = 4 years old. Ty is currently (2 * 4) + 4 = 12 years old. In 5 years, Frank will be 12 * 3 = 36 years old. The answer is 36.
