This question is solved using proportions, as the table gives us the number of words per page given the dimensions, and the number of pages, which lets us calculate the number of words.
Doing this, we get that the story will be composed of 792,800 words.
-------------------------------------------
- According to the table, pages of dimensions 8.5in x 11in have 800 words.
- The book has 991 pages, of 8.5in x 11in dimensions.
Thus, considering that there will be 991 pages, each with 800 words, the total number of words in the story will be of:

The story will be composed of 792,800 words.

two intersecting lines can only have 1 solution.
We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
N/4.3 = 9.4
4.3 × n/4 = 9.4 × 4.3
n = 40.42
