Question

A certain kind of stapler holds 210 staples when fully loaded. A box of staples for this kind of stapler contains 5,000 staples. If you use a full box of staples and fully load as many empty staplers as possible, how many staples will be left in the box?

Answer 1

This is simple, just divide 5,000 by 210

5000 ÷ 210 = 23.809

23.809 = 23.81

23.81 = 23.8

23.8 = 23

Thats for staplers being full, now for how many is left

It would be 170, for that, you have to subtract:

5000 - (210 · 23) = 170

5000 - 4830 = 170

170

Your answer would be:

23 staplers would be full and 170 staples were left
