Fundraiser. The Biology Club plans to have a fundraiser for which $8 tickets will be sold. The cost of room rental and refreshments is $175. Find and graph the function p=f(n) that gives the profit from the fundraiser when n tickets are sold. Notice that f(0)= -$175, that is, the cost of room rental and refreshments must be paid regardless of how many tickets are sold. How many tickets must be sold to break even (zero profit)?
As there are no given values to graph, just the function, we give values of numbers of tickets sold (n) and substitute them into the equation to obtain the profit (p).
