A chef has served 58 adults, 35 fewer children than the number of adults, and twice as many seniors as children. What is the total number of guests served?
Let's think: The chef has served 58 - 35 = 23 children. The chef has served 23 x 2 = 46 seniors. Therefore, the total number of guests that the chef has served is 58 + 23 + 46 = 127.. The answer is: 127.

Emily just purchased 2 pairs of curtains for $30.00 each and 9 wall prints at $15.00 each. The store also offers an installation service. For $50.00 they will come to your house and professionally hang your curtains and prints. If Emily agrees to this service, how much will her entire order cost?
Let's think: She buys 2 pair of curtains for $30.00 each so that's 2 * 30 = $60.00. She buys 9 wall prints at $15.00 each so that's 9 * 15 = $135.00. The curtains cost $60.00, the prints are $135.00 and the installation service is $50.00 for a total of 60 + 135 + 50 = $245.00.. The answer is: 245.

There are 20 students in a class. Only one-fourth of the students stayed in the classroom while the rest went to the playground. Of those who went to the playground, one-third are boys. How many girls are there on the playground from this class?
Let's think:
Out of the 20 students, 20 x 1 / 4 = 5 students stayed in the classroom. While 20 - 5 = 15 students went to the playground. Out of these 15 students, 15 x 1 / 3 = 5 are boys. Therefore, 15 - 5 = 10 girl students from this class are in the playground.. The answer is: 10.
