Question 34082: The year y when sales were s million dollars for a particular electronics company can be modeled by the radical equation
y=1.3√s-4-7
where y = 1 represents 2001, and so on.
Use the model to predict the sales for 2006 to the nearest tenth of a million.

A) $ 106.0 million

B) $ 102.0 million

C) $ 104.0 million

D) $ 108.0 million

You can put this solution on YOUR website!
y=1.3√(s-4)-7
where y = 1 represents 2001, and so on.
Use the model to predict the sales for 2006 to the nearest tenth of a million.
6=1.3sqrt(s-4)-7
13=1.3sqrt(s-4)
10=sqrt(s-4)
Square both sides to get:
100=s-4
s=104
