Respuesta :

Some things you need in your respond is:

- Although the percentage might eventually round to 100%, it is not possible to have 100% of the phones working.
- This is because the model began when only 3 out of 10 phones were working, so there are 7 phones that were not working.
- In other words, the numerator and denominator of the expression are never the same, so the expression is never equal to 1 or 100%.

The percentage of 100% will never be achieved, even if the production of the phone increased.

The percentage can be explained as:

  • The numerator and denominator of the given expression cannot be the same, thus, the expression never equals 100%.

  • The percentage might be rounded off to 100%, but it is not possible to have the production or increment in the phone working to be 100%.

  • The number of phones out of ten that were working is three, such that the remaining seven phones were not working. The percentage will be nearer to 3/10.

Thus, the percentage cannot be reached 100%, even if the phone production increases.
