For a certain company, the cost for producing X items is 40x+300 and the revenue for selling x items is 80x-0.5x^2. The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!
Part a: Set up an expression for the profit from producing and selling x items. we assume that the company sells all of the items that it produces. ( Hint: it is a quadratic polynomial).
PartB: find two values of x that will create a profit of $300.
Part C: is it possible for the company to make a profit of $15,000.
x=

I don’t know the answer I just need some points to ask more questions

Step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer:

a=9
