He takes 2 pages of notes every day for each of his 5 classes so that's 2 * 5 = 10 pages of notes. He takes 10 pages of notes every day for 5 days so that's 10 * 5 = 50 pages of notes. If he takes 50 pages of notes every week for 6 weeks that's 50 * 6 = 300 pages of notes. His notebook paper comes 100 pages per pack and he has taken 300 pages of notes so he used 300 / 100 = 3 packs of notebook paper.
The answer: 3

First find the amount paid just for the per - minute fee, which is $146 - $20 = $126. Then divide that number by the per - minute rate to find the number of minutes: $126 / $7 per minute = 18 minutes.

Reverse engineering the question: Gnuff charges a flat rate of $20 per tutoring session plus $7 per minute. The total amount paid for Gnuff for tutoring for one session is $146. How many minutes did Gnuff tutor for?

If X = "Price of Reuben" We know that 10(X) + 5(X + 2) = 55. Therefore 10X + 5X + 10 = 55. Therefore 15X = 45. Therefore, the price of a Reuben is $3 because 45 / 15 = 3. The price of pastrami is $5 because 3 + 2 = 5.
The answer: 5
