Question 202985: An automobile manufacturer is introducing a new fuel-efficient model and estimates the demand for the car as N=54000ln(6t+8) where N is the estimated number of cars to be sold and t is the number of years after the car is introduced. When will the demand be 215,000 cars?

You can put this solution on YOUR website! An automobile manufacturer is introducing a new fuel-efficient model and estimates the demand for the car as N=54000ln(6t+8) where N is the estimated number of cars to be sold and t is the number of years after the car is introduced. When will the demand be 215,000 cars?
-------------------------------------------------------
215,000 = 54000*ln(6t+8)
ln(6t+8) = 0.398
6t+8 = e^0.398
6t+8 = 1.4891
Comment: This doesn't make any sense
t would be negative, meaning the demand would be 215000
before the car is introduced.
