Question

A business has found that it can sell 710 items if it sets its price to $61.38. However, if it lowers its price to $44.27, it can sell 880 items.

(a) Find the linear demand equation (price function) for selling  x items. (round to 4 decimal places)

p(x)=px=    


It costs the business $11.13 per item to produce and they have $3,450 in overhead each month.
(b) Find the linear Cost, and quadratic Revenue and Profit functions for producing/selling x items: (round to 4 decimal places)

C(x)=Cx=   x+x+  

R(x)=Rx=    x2+x2+  x+x+  

P(x)=Px=    x2+x2+  x+x+  

 

(c) Consider the maximum profit the company can make:

To maximize their profit, they should sell   items at a price of $   each and they will make $  in profit.
