[Question]Bill and Phil are firehouse Dalmatians. Bill has one less than twice as many spots as Phil. If they have 59 spots combined, how many spots does Bill have?
[Answer]If b is the number of spots Bill has and p is the number of spots Phil has, we know that b + p = 59. We also know that b = 2p - 1. We can substitute the second equation into the first equation to get: 2p - 1 + p = 59. Combining like terms, we get 3p - 1 = 59. Adding 1 to both sides, we get 3p = 60. Dividing both sides by 3, we get p = 20. Substituting this back into the equation b = 2p - 1, we get b = 2 * 20 - 1 = 40 - 1 = 39. The answer is 39.
Q: Janet needs 5 tickets to ride the roller coaster and 3 tickets to ride the giant slide. How many tickets does she need to ride the roller coaster 7 times and the giant slide 4 times?
A: First find how many tickets she needs for the roller coaster: 5 tickets / ride * 7 rides = 35 tickets. Then find how many tickets she needs for the giant slide: 3 tickets / ride * 4 rides = 12 tickets. Then add the number of tickets she needs for each ride to find the total number of tickets she needs: 12 tickets + 35 tickets = 47 tickets. The answer is 47.
Question: There are 20 stickers on a page. If you have 12 pages of stickers but lose one of the pages, then how many stickers would you have?

[Question]Ron's baseball team scored 270 points in the year. There are 9 players on the team. If 5 of them averaged 50 points each, how many points did the remainder average?
[Answer]The first five players scored a total of 250 points because 5 x 50 = 250. There are 4 players left because 9 - 5 = 4. The 4 remaining players scored 20 points because 270 - 250 = 20. The 4 remaining players averaged 5 points because 20 / 4 = 5. The answer is 5.
Q: Hillary always buys the Wednesday, Thursday and Friday editions of the local newspaper for $0.50 each. On Sunday, she spends $2.00 to get that copy. How much does she spend on the newspaper over 8 weeks?
A: She buys Wednesday, Thursday and Friday's paper for $0.50 each so that's 3 * .50 = $1.50. She spends $1.50 for the weekday papers and $2.00 for the Sunday paper for a total of 1.5 + 2 = $3.50 a week. Over 8 weeks she spends 8 * 3.5 = $28.00. The answer is 28.
Question: A monitor is 21 inches by 12 inches. There are 100 dots per inch. How many total pixels are there?
