The author of a book was told that he would have to cut the number of pages by 13% for the book to sell at a popular price and still make profit. If these cuts were made what percent of the original number of pages was the final version?

If this book begins as 100% and he is asked to cut 13%, we need to subtract 100% - 13%. This is the amount that remains.

`100% - 13% = 87%` .

`87%` of the original number of pages are in the final version.

**If the book began with "x" pages, then the book after the cut would have 87% of x pages remaining, or `.87x` **

If the author cuts 13% of his book, then 87% of the original pages will remain.

For example, if the book originally has 100 pages, a 13% cut would be equivalent to 13 pages (100 * .13 = 13).

100 pages minus 13 pages is 87 pages. In order to find the percentage, the remaining number of pages is divided by the initial number of pages. The quotient is then multiplied by 100:

87/100= .87

.87 *100%= 87%

87% of the original pages will remain in the final version.

100% minus 13% equal 87%

so 87% of the original book would stay in the final version
