Answer:
Step-by-step explanation:
The polynomial given is: 
<em><u>Grouping the first 2 terms together and the last 2 terms together and taking common, we have:</u></em>
This is the complete factorization.
For the 1st hour the cost is $50 whatever is the duration (providing it's 1 hour max.
From one hour and onward the cost becomes an additional $25 per quater of an hour.
If y is the cost and x the number of hours, then the equation becomes :
y =50 + 0.25.x or y =1/4x + 50

1) 9,06
2) 85,3018
3) 0,052121
4) 0,917123
5) 17,9807
6) 2267,96
7) 169,07
8) 0,211338

n = -9/2 = -4.5</span>
If you don't include the outlier (50) then it is 79.7
