Question 73573
finance. If the inventor in exercise 53 charges $4 per unit, then her profit for producing and selling x units is given by the function
P(x)= 2.25x - 7000
(a) What is her profit if she sells 2000 units?
(b) What is her profit if she sells 5000 units?
(c) What is the break-even point for sales?
-----------------
a) P(2000) = 2.25*2000-7000
=4500-7000
=-$2500
She loses $2500
================
P(5000) = 2.25*5000-7000
=11250-7000
=$4125
===========
If 2.25x-7000=0
Then 2.25x = 7000
x=3112 units
=========
