Don't worry about what problem number 53 says. Here's what you've got to do:
a. what is her profit if she sells 2000 units?
-Find P(2000). Plug 2000 in for x in your profit function and see what you get:
P(2000) =2.25(2000)-7000
b. what is her profit if she sells 5000 units?
-Nearly the same as a. Find P(5000). Plug 5000 in for x in your profit function and see what you get:
P(5000) =2.25(5000)-7000
c. what is the break-even point for sales?
-Set P(x) equal to 0 and solve for x. Like this:
2.25x - 7000 = 0
