Q: Chris’s internet bill is $45 per month for 100 GB and $0.25 for every 1 GB over. His bill for this month is $65. How many GB over was Chris charged for on this bill?
A: Let G stand for the number of GB billed, so the total bill is $0.25G + $45 flat rate charge = $65 total bill. Now we will solve for G. $0.25G + $45 flat rate - $45 = $65 - $45. This simplifies to $0.25G = $20. $0.25G / $0.25 = $20 / $0.25. G = 80 GB were charged on this bill. The answer is 80.
Question: Ethan is reading a sci-fi book that has 360 pages. He read 40 pages on Saturday morning and another 10 pages at night. The next day he read twice the total pages as on Saturday. How many pages does he have left to read?
Answer: Ethan read a total of 40 pages + 10 pages = 50 pages on Saturday. On the next day, he read a total of 50 pages x 2 = 100 pages. The total number of pages that Ethan had read is 50 pages + 100 pages = 150 pages. Therefore, Ethan has 360 pages - 150 pages = 210 pages left to read. The answer is 210.
[Question]Tom, an avid stamp collector, has 3,000 stamps in his collection. He is very sad because he lost his job last Friday. His brother, Mike, and best friend, Harry, try to cheer him up with more stamps. Harry’s gift to Tom is 10 more stamps than twice Mike’s gift. If Mike has given Tom 17 stamps, how many stamps does Tom’s collection now have?
[Answer]Twice the number of stamps given by Mike is 17 stamps * 2 = 34 stamps. Harry therefore gave Tom 10 stamps + 34 stamps = 44 stamps. Combining both gifts gives a gift total of 44 stamps + 17 stamps = 61 stamps. The total number of stamps in Tom’s collection is now 3000 stamps + 61 stamps = 3061 stamps. The answer is 3061.

Question: Jordan's dog, Max, was born on the same day that Luka turned 4 years old. Luka is exactly 2 years older than is Aubrey. On Aubrey's 8th birthday, how many years old was Jordan's dog, Max?
Answer: If Luka is exactly 2 years older than is Aubrey, then on Aubrey's 8th birthday, Luka was 8 + 2 = 10 years old. If Jordan's dog, Max, was born on the same day that Luka turned 4 years old, then when Luka was 10 years old, Max was 10 - 4 = 6 years old. The answer is 6.
Q: On her birthday, Avianna bought red candles and blue candles in the ratio of 5:3. If Avianna had 45 red candles on her birthday, how many blue candles did she have?
A:
If the ratio of red candles to blue candles Avianna bought was 5:3, then the total ratio was 5 + 3 = 8. If 5 represented 45 candles in the total ratio, then 8, the actual ratio, represents 8 * 45 = 360 divided by 5 is 360 / 5 = 72 candles. If the total number of candles was 72, then the number of blue candles is 72 candles - 45 candles = 27 candles. The answer is 27.
