A teacher distributes different mathematics books to students for their study and revision. She gave out similar copies of 4 Trigonometry, 6 Algebra, 3 Pre-calculus, 9 Statistics, and 4 Geometry books. A Trigonometry book has 400 more pages than an Algebra book, a Pre-calculus book has twice the number of pages as an Algebra book, a Statistics book has 112 times the number of pages as an Algebra book, and a Geometry book has 150 more pages than an Algebra book. 1. Letting p to represent the number of pages in an Algebra book, write the number of pages of each of the trigonometry, algebra, pre-calculus, and statistics and geometry book in terms of p.

2. Write a linear expression that represents the total number of pages in all the books that were given out.

3. Write down a simplified form of the expression in (2) above.

4. If the total number of pages in all the books is 8900 write an equation to represent this.

5. Find the value of p.

6. Find the number of pages in an algebra book.

7. Find the number of pages in the other books

I don't understand this assignment in the slightest. My brain is unable to wrap itself around it-
