Five workers have been hired to complete a job.  If one additional worker is hired, they could complete the job $4$ days earlier.  If the job needs to be completed $20$ days earlier, how many additional workers should be hired?

So, right now there are \(5\) workers. They need to get the job completed 20 days earlier.

 

Since each additional worker adds on \(4\) days, we simply have

 

\(\frac{\text{Number Of Days}}{\text{Days Saved Per Worker}}\). Thus, we can plug in \(20/4 = 5\) workers.

 

So our answer is 5 workers. 

 

Thanks! :)
