[Question]Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled?
[Answer]If the first 100 miles took one hour, then let's say the next 300 miles took x hours. if 100 miles = 1 hour, then 300 miles = x. To find the number of hours traveled for the 300 miles, x = 300 * 1 / 100. x = 3 hours. The total number of hours will be 3 + 1 = 4 hours. The answer is 4.
Q: If Lucy would give Linda $5, Lucy would have the same amount of money as Linda. If Lucy originally had $20, how much money did Linda have at the beginning?
A: After giving $5, Lucy has $20 - $5 = $15 left. Since Linda has $15 after receiving $5, then she had $15 - $5 = $10 at the beginning. The answer is 10.

Q: To pass the time while she is waiting somewhere Carla likes to count things around her. While she is waiting for school to start on Monday she counts the tiles on the ceiling--38. While she is waiting for everyone to finish their tests after she has handed in hers, she counts the books in the room--75. On Tuesday Carla counts all the tiles twice in a row and she counts the books three times in a row when she has to wait for a long time for the teacher to finish handing out the graded tests. If every time Carla counts something counts as once, how many times has Carla counted something on Tuesday?
A: When Carla was waiting on Monday she counted 38 ceiling tiles and on Tuesday she counted them twice, 38 ceiling tiles x 2 = 76 times she counted a ceiling tile. She also counted 75 books in the room on Monday and counted them three times in a row on Tuesday, 75 books x 3 = 225 times she counted a book. On Tuesday Carla counted the ceiling tiles 76 times + counted books 225 times = 301 times Carla counted something on Tuesday. The answer is 301.

Christopher has 64 quarters so he has 64 * .25 = $16.00. Karen has 32 quarters so she has 32 * .25 = $8.00. If Christopher has $16.00 and Karen has $8.00 then Christopher has 16 - 8 = $8.00 more than Karen. The answer is 8.
