Question

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

Answer 1

This is simple to solve as all we need to do is setup a basic equation. An equation that could represent this is
`3127+x=5000` where x is equal to the amount of wire left on the reel.


`3127+x=5000`

`-3127`
`-3127`

`x=1873`

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