Q: The American Academy of Pediatrics recommended no more than 2 hours of screen time each day for children. Mrs. Merril wants to follow a 2-hour screen time for her child. How many minutes will she allow her child to use his gadget this evening if he already used his gadget for 45 minutes in the morning?
A: Mrs. Merril wants to follow 2 hours x 60 minutes / hour = 120 minutes screen time. Since her child already used up 45 minutes, he is allowed to use his gadget this evening for 120 minutes - 45 minutes = 75 minutes. The answer is 75.
Question: Meryll wants to write 35 multiple-choice questions and 15 problem-solving questions for her Chemistry class. She already has written 2/5 of the multiple-choice and 1/3 of the problem-solving questions. How many more questions does she need to write for both multiple-choice and problem-solving?
Answer: Meryll has written 35 questions x 2 / 5 = 14 multiple - choice questions. While she has written 15 questions x 1 / 3 = 5 problem - solving questions. The total number of questions that Meryll has to write is 35 questions + 15 questions = 50 questions. Meryll has written a total of 14 questions + 5 questions = 19 questions. Hence, she needs to write 50 questions - 19 questions = 31 questions more. The answer is 31.

Q: Vann is a veterinarian. Today he is going to be doing dental cleanings only. Dogs have 42 teeth, cats have 30 teeth and pigs have 28 teeth. If he is to do 5 dogs, 10 cats and 7 pigs, how many total teeth will Vann clean today?
A: First let's find the number for each animal separately, 42 teeth per dog * 5 dogs = 210 teeth for dogs. Then cats total will be 30 teeth per cat * 10 cats = 300 teeth in total for cats. Finally, the number for pigs is 28 teeth per pig * 7 pigs = 196 teeth in total for pigs. So the total in all is 210 teeth + 300 teeth + 196 teeth = 706 teeth in total. The answer is 706.
Question: A cake has 8 slices and each slice contains 347 calories. A pan of brownies has 6 brownies and each slice contains 375 calories. How many more calories does the cake have?
