Reasoning and answer: 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: 80

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: 210
Reverse engineering the 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?


Reasoning and 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: 3061

Sunny has a total of 8 - 2 = 6 cakes. Sunny will use a total of 6 * 6 = 36 candles.
The answer: 36
Reverse engineering the question: Sunny bakes 8 cakes. Then she gives away 2 cakes. Sunny wants to put candles on the remaining cakes. If she puts 6 candles on each cake, how many candles will she use in total?


Reasoning and 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: 6

Reasoning and answer: 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: 27
