Answer:
There are 500 staples in each package.
Explanation:
This is a simple problem which requires us to tell number of staples each package have. The total number of staples in the catoon and the total number of staples that each package have is given in the question. So we can easily calculate total number of staples that each package have by dividing total number of staples in the cartoon by number of staples each packet have i.e.
25,000/50 = 500
