Question: When Doctor Lindsay works in her office, she usually sees 4 adult patients and 3 child patients every hour. If the cost for an adult's office visit is $50, and the cost for a child's office visit is $25, how much money, in dollars, does Doctor Lyndsay receive in a typical 8-hour day for seeing all her patients?
Answer: For 4 adult patients per hour, Dr. Lindsay receives 4 * 50 = 200 dollars per hour. For the 3 child patients per hour, Dr. Lindsay receives 3 * 25 = 75 dollars per hour. Thus, Dr. Lindsay receives 200 + 75 = 275 dollars per hour. In an 8 - hour day, Dr. Lindsay receives 8 * 275 = 2200 dollars. The answer is 2200.
[Question]Erin is sorting through the library books to decide which ones to replace. She finds 8 less than 6 times as many obsolete books as damaged books. If she removes 69 books total, how many books were damaged?
[Answer]Let o be the number of obsolete books and d be the number of damaged books. We know that o + d = 69 and o = 6d - 8. Substituting the first equation into the second equation, we get 6d - 8 + d = 69. Combining like terms, we get 7d - 8 = 69. Adding 8 to both sides, we get 7d = 77. Dividing both sides by 7, we get d = 11. The answer is 11.
Q: During the Christmas holidays, all shops are closed for 3 days. During each day during this time, a shop called "Surprise" could have earned 5 thousand dollars. How much potential revenue did the "Surprise" shop lose during 6 years of activity?
A: In one day the shop is losing 5 thousand dollars, so during three days, the losses are 5 * 3 = $15,000. Christmas holidays are once a year, so in 6 years the shop "Surprise" could have earned another $15,000 * 6 = $90,000. The answer is 90000.
Question: The number of female students in the school hall is 4 times as many as the number of male students. If there are 29 male students, and there are 29 benches in the hall, at least how many students can sit on each bench for them to all fit in the hall?
Answer: The number of female students is 4 times 29: 4 * 29 = 116. There are a total of 29 + 116 = 145 students in the hall. There are 29 benches so each bench should take 145 / 29 = 5 students. The answer is 5.
