Question

Five workers have been hired to complete a job. If one additional worker is hired, they could complete the job $8$ days earlier. If the job needs to completed $28$ days earlier, how many additional workers should be hired?

Answer 1

Let's assume that the initial number of workers is 5, and they take a certain number of days, denoted by "x," to complete the job.

If one additional worker is hired, the job can be completed 8 days earlier. This means that the new number of workers is 5 + 1 = 6, and the number of days it takes to complete the job is x - 8.
