HELPA broken scale shows a false weight that is always less than the actual weight by the same number of ounces. When a box is put on the scale, it shows 15 ounces. When a bag is put on the scale, it shows 12 ounces. When the box and the bag are put on the scale together, it shows 31 ounces. What is the actual weight of the box?

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
