1.A sports team is throwing an end-of-season party at the fitness club. The costs associated with the party include an $85 flat fee for the room rental, and a $12.95 per person charge for the Italian buffet. A 15% tip must be added to the cost of the food. Express the total cost for the party as a function of the number of people attending. Graph this function in an appropriate window, labeling axes and scale. If the budget for the party is $1,800, how many people can attend? (You may solve this last question either algebraically or graphically.)
