First the formula for finding the profit is given.
P(x) = 2.25x - 7000
P(x) = the total profit earned (once you plug in the value of x)
x = the number of units
You need to just plug in the number of units for "x".
(a) What is her profit if she sells 2000 units?
P(x) = 2.25(2000) - 7000
= -$2,500 (loosing money)
(b) What is her profit if she sells 5000 units?
P(x) = 2.25(5000) - 7000
= $4,250 (profit)
(c) What is the break-even point for sales?
Sorry, this one I am not sure of!!
