The total cost of renting a banquet hall is a function of the number of hours the hall is rented. The owner of the banquet hall
charges $85 per half hour up to a maximum of 4 hours plus a $50 cleaning fee. What is the greatest value in the range for this situation? What is the slope of the line that passes through the points (26, 7) and (-39, 12)
It would be $390 for the 4 hours and the cleaning fees. And the slope would be -13 if you are going from 12 to 7 but would be 13 if you are going from 7 to 12...
