Solve.John owns a hotdog stand. He has found that his daily profit is represented by the equation 
with P being the profit in dollars, and x the number of hotdogs sold per day. (i) Graph the equation P = -x2 + 68x + 83.(ii) How many hotdogs must he sell per day to earn the most profit?(iii) Describe how the height of the graph changes as sales increase.
What will be an ideal response?
(i)
(ii) John must sell 34 hotdogs per day to maximize his profit.
(iii) The height of the graph increases when 0 to 34 hotdogs are sold but then decreases for sales of more than 34 hotdogs.
