An appliance company determines that in order to sell x dishwashers, the price per dishwasher must be p = 420 - 0.3x. It also determines that the total cost of producing x dishwashers is given by C(x) = 5000 + 0.3x2. How many dishwashers must the company produce and sell in order to maximize profit? g

Answer:

The number of dishwasher to produce is  [tex]x = 688 \ or \ x = 12[/tex]

Step-by-step explanation:

From the question we are told that

     The price per dishwasher is  [tex]p = 420 - 0.3x[/tex]

     The total cost of producing x  dishwasher is  [tex]C(x) = 5000 + 0.3 x^2[/tex]

Now at the question we can deduce that the price for x dishwasher will be  mathematically evaluated as  

      [tex]P_t(x) = x * p[/tex]

      [tex]P_t(x) = x * (420 - 0.30 x)[/tex]

      [tex]P_t(x) = 420x - 0.30x^2[/tex]

Now the profit from selling the dishwasher can be mathematically represented as

         [tex]P (x)= P_t (x ) - C(x)[/tex]

substituting for  [tex]P_t (x ) \ and \ C(x)[/tex]

         [tex]P(x) = 420 x -0.3x^2 - [5000 + 0.3x^2][/tex]

          [tex]P(x) = 0.6x^2 - 420 x + 5000[/tex]

Solving for x using the quadratic formula we have that

         [tex]x_1 = 688 \ or \ x = 12[/tex]

So the for maximum profit and reduce cost price the number of  dishwasher the company would produce is   [tex]x = 688 \ or \ x = 12[/tex]
