This is a linear relation, and you're given 2 points.
With 2 points you can plot the entire line. The points are:
(6.7,100) and
(10.2,80) where each unit on the x-axis is times 1 million
and the y-axis is dollars
The formula is:

I'll say that
(,) = (6.7,100)
(,) = (10.2,80)

Multiply both sides by

If or,the price is $75

They can expect to sell 11,075,000 MP3 players
