(Enter your answers using interval notation.) P = 2.34x- increasing modeled by decreasing (b) If you owned the cinema, what price would you charge to obtain a maximum profit for popcorn? Explain your reasoning. You should charge the price that yields sales of x = 32,760 bags of popcorn. Since the function changes from increasing to decreasing at x = 32,760, the maximum profit occurs at this value. O You should charge the price that yields sales of x= 32,260 bags of popcorn. Since the function changes from increasing to decreasing at x = 32,260, the minimum profit occurs at this value. O You should charge the price that yields sales of x = 32,760 bags of popcorn. Since the function changes from decreasing to increasing at x = 32,760, the minimum profit occurs at this value. O You should charge the price that yields sales of x= 33,260 bags of popcorn. Since the function changes from decreasing to increasing at x = 33,260, the maximum profit occurs at this value. O You should charge the price that yields sales of x= 32,660 bags of popcorn. Since the function changes from decreasing to increasing at x = 32,660, the minimum profit occurs at this value.
