Question 1166505: Sales of a portable MP3 players grr approximately exponentially from $0.05 billion in 2001 to $0.65 billion in 2005. Predict the sales of the MP3 in 2007 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! (0, 0.05)
(4, 0.65)
y=ab^x
0.05=ab^0 so a is 0.05
0.65=0.05b^4
13=b^4
b=1.899 or 1.9
2007 is x=6
y=0.05*1.9^6
=$2.35 billion.
