[Question]Bailey needs to buy 2 new sets of towels for the guest bathroom and 4 new sets for her master bathroom. The set of towels for the guest bathroom are $40.00 each and the master bathroom set is $50.00 each. The store is currently offering 20% off so how much will Bailey spend on towel sets?
[Answer]She needs 2 sets of guest towels that are $40.00 each so that's 2 * 40 = $80.00. She needs 4 sets of master bath towels that are $50.00 each so that's 4 * 50 = $200.00. Together, the towels will cost 80 + 200 = $280.00. The store is offering 20% off of her $280.00 towels so that's 280 * .20 = $56.00 discount. Her $280.00 towels have a $56.00 discount making them 280 - 56 = $224.00. The answer is 224.
Q: Mike can type 65 words per minute. Due to a minor accident, Mike cannot use his right hand for a while so that his typing speed is now 20 words less per minute. If he is supposed to type a document with 810 words, how many minutes will it take him to finish typing the document?
A: After the accident, Mike can only type 65 words / minute - 20 words / minute = 45 words / minute. So, he will be able to finish typing the document in 810 words / 45 words / minute = 18 minutes. The answer is 18.
Question: Lance has 70 cents, Margaret has three-fourths of a dollar, Guy has two quarters and a dime, and Bill has six dimes. How many cents do they have combined?
Answer: Margaret has 100 * 0.75 = $0.75. Guy has $0.25 + $0.25 + $0.10 = $0.60. Bill has 6 * $0.10 = $0.60. Lance, Margaret, Guy and Bill have $0.70 + $0.75 + $0.60 + $0.60 = $2.65. Thus they have $2.65 * 100 = 265 cents. The answer is 265.

[Question]In a national park, the number of redwoods is 20% more than the number of pines. If there are 600 pines in the national park, calculate the total number of pines and redwoods that are there.
[Answer]
If there are 600 pines, there are 20 / 100 * 600 = 120 more redwoods than pine trees in the national park. In total, there are 120 + 600 = 720 redwoods in the national park. Altogether, there are 720 + 600 = 1320 pines and redwoods in the national park. The answer is 1320.
