0.5 hour 2
Answer:
See explanation below.
Step-by-step explanation:
Assuming the following function:

Where y represent the sales and t the years after a particular model is introduced.
For this case if we find the domain for this function we have this:
Since the neatural log for negative numbers or 0 is not defined.
So then 
And the range on this case is all the possible reals.
The sales are equal to 0 when:

If we exponential both sides we got:


So then the x intercept is
. We don't have y intercept since the function not touch the y axis.
And we don't have a relative maximum or minimum since the function is increasing over the interval of all the reals.
The plot of the function is on the figure attached.
Answer:
let the hotel charge before tax for second hotel be x
then the hotel charge before tax for first hotel = x+1500
tax of first hotel = 7.5% * (x+1500) = (7.5x+11250)/100
tax from second hotel= 7% of x = 7x/100
total tax = 547.50
7x/100 + (7.5x+11250)/100 =547.50
14.5x = 54750-11250
14.5x= 43500
x= 3000
hotel charge in first city = 4500
in second city =3000
