Question 392652: Hello. I recently stumbled across your website while trying to figure out one of my Algebra assignments. I am stumped. I think I came up with the right polynomial 100x-x^2+100? When I go to solve the 50000 phones sold in the problem I can't figure it out and it is the last question on my homework assignment due today. Please help!
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.
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.)

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
