Maybe the way the equation is given is confusing you... x is a variable in the equation which represents the number of units sold. P(x) is an expression of the Profit in terms of number of units sold. So, to figure out the profit, just plug in the given value for number of unit sold, which is x, and solve the equation:
a.) what is her profit if she sells 2000 units?
Plug in 2000 for x:
Note the answer is negative, so she lost money selling only 2000 of these.
b.)what is her profit if she sells 5000 units?
Plug in 5000 for x:
I will let you do the math to finish this one...
c.) what is the break even point for sales?
The break even point is by definition when the profit is exactly zero. So equate the given expression to zero, and solve for x:
Since you can't sell a tenth of a unit, just round it to the nearest whole unit:
