If it takes 3127 feet of computer cable to wire an office building how much cable will left if the wire is taken from a 5000 foot reel

This is simple to solve as all we need to do is setup a basic equation. An equation that could represent this is  where x is equal to the amount of wire left on the reel.


 


Using this information, we can see that there are 1,873 feet of wire left on the reel.

Ithink it’s b, hope this .
