Step-by-step explanation:
Answer:
(1, 3) and (4,0)
Step-by-step explanation:
The quadratic function is 
We can rewrite in the form 
The graph is obtained by shifting the parent quadratic function 3 units right and 1 unit down to obtain the parabola shown in the attachment.
The straight line also have equation 
The slope is -1 and y-intercept is 4.
We can easily graph this straight line on the same graph as shown in the attachment.
The two graphs intersected at (4,0) and (1,3).
The solution set is therefore {(x,y)|x=4,y=0 or x=1,y=3}
Since the equation is:
<span>P(x)=-5x^2+40x-300
Solving the equation by using the calculator, the values for x are:
x = 4.72
Therefore, the company must sell 8 items per week to maximize the profit.
