Answer:
I am pretty sure that it is a
You must take the 248.50 and multiply it by .25 then you subtract the answer from 248.50 and end up with 186.4 then you multiply that number by .05 and add that to the 186.4 and the answer you should get is 195.69
If a polynomial "contains", in a multiplicative sense, a factor
, then the polynomial has a zero at
.
So, you polynomial must contain at least the following:

If you multiply them all, you get

Now, if you want the polynomial to be zero only and exactly at the four points you've given, you can choose every polynomial that is a multiple (numerically speaking) of this one. For example, you can multiply it by 2, 3, or -14.
If you want the polynomial to be zero at least at the four points you've given, you can multiply the given polynomial by every other function.
