Question 469378: 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 given by the expression 100x. That is,
Revenue = 100x
Use the following knowledge to determine the profit by subtracting the expenses from the revenue:
a.Give a polynomial expression that can be used to compute the profit. Briefly explain how this was done.
b.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.). Show the steps of the computation. After making the computation, interpret the results in real-life terms

Profit=100x-(x2+800)
P=-x2+100x-800
f(50)=-(50)2+100(50)-800
""=5000-2500-800=5000-3300=1700
Which means the profit off of 50000 smartphones is $1,700,000..
