A consumer electronics company sells 6.7m MP3 Playerss per month at 100$ a piece. When the price is lowered to 80$ a piece the company sells 10.2m. How many MP3 Players can the company expect to sell per month at a price of 75$ a piece?
-----
You have two points: (100,6.7m) and (80,10.2m)
--------
slope = k = (10.2-6.7)/-20 = -0.175
-------------------
Form: N(x) = kx + b
---
Solve for "b":
6.7m = -0.175*100 + b
6.7 = -17.5 + b
b = 24.2
============
N(x) = -0.175x + 24.2
---
N(75) = -0.175*75+24.2
N(75) = 11.075 million
=========================
