Question 392652
Your company has asked you to research the smartphone competitive market. Through research, you have modeled the industry data and found that the cost (in thousands of dollars) of producing a certain number of smartphones can be given by the following equation:

Expenses = x2 + 800

where x = the number of smartphones in thousands.

The revenue (also in thousands of dollars) generated in selling the same amount is 100x. That is,

Revenue = 100x

Use the following knowledge to determine the profit by subtracting the expenses from the revenue:

   1. Give a polynomial expression that can be used to compute the profit.
100x-(x^2+800)= Profit 

   2. Use the expression you just derived to compute the profit if 50,000 smartphones are sold. (Note: Remember that the profit is expressed in thousands of dollars, so a computed value of, say, 30 means $30,000.)

 100*50-(50^2+800)= Profit
5000-(2500+800)= Profit
5000-2800= Profit
$2,200,000= profit
