A consumer electronics company sells 6.7 million MP3 players per month at a price of $100 apiece; when the price is lowered to $80, the company sells 10.2 million players per month. How many MP3 players can the company expect to sell per month at a price of $75?
(100, 6.7) and(80,10.2)
slope = (10.26.7)/(80100)=7/40
form y=mx+b
6.7= )7/40)*100 +b
b= 6.7 +17.5
b= 24.2
equation:
#sold = (7/40)x + 24.2 million where x is price per unit.
#(75)=(7/40)*75+ 24.2
# (75)= 11.075 million
Can this problem be graphed and how?

Your work is correct
for graphing use :
horizontal axis x , x is price
vertical axis is p, p for players in millions
Use points (0, 24.2) and (80, 10.2)
