Answer:
The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600
Step-by-step explanation:
Given
First, we calculate the revenue.
Let x be the change in rate.
i.e.
For every 2x increment in price (p) i.e. p + 2x
There will be 4 fewer rooms (n) i.e. n - 4x
So, the revenue is updated as:
So:
So:
Expand
Reorder
The maximum of a function is calculated as:
In:
So:
To get the maximum revenue;
Substitute 40 for x in
The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600
Well you have to do PEMDAS
So we have an exponent so that will turn into a positive X
X+4x=10
So now we combine our X's together to get 5X=10
Now we divide both sides by X which gives us 2
