Question: Yvonne and Janna were writing their 1000-word pair research paper. Yvonne was able to write 400 words while Janna wrote 150 more words than Yvonne. When they edited their paper, they removed 20 words and added twice as many words as they removed. How many more words should they add to reach the research paper requirement?
Answer: Janna wrote 400 + 150 = 550 words. Together, they wrote 400 + 550 = 950 words. They have 950 - 20 = 930 words left after omitting 20 words. Then 20 x 2 = 40 words were added during the editing. Overall, they have 930 + 40 = 970 words. Thus, they should add 1000 - 970 = 30 more words. The answer is 30.

Question: Stephen made 10 round trips up and down a 40,000 foot tall mountain. If he reached 3/4 of the mountain's height on each of his trips, calculate the total distance he covered.
Answer: Up a mountain, Stephen covered 3 / 4 * 40000 = 30000 feet. Coming down, Stephen covered another 30000 feet, making the total distance covered in one round to be 30000 + 30000 = 60000. Since Stephen made 10 round trips up and down the mountain, he covered 10 * 60000 = 600000. The answer is 600000.
