Explanation:
First, for 80 room charged at $60 per room ,all rooms are occupied
Let the demand function, expressed by p , the price in dollars charged for each room per day, as a function of x as,
p(x)=$60x ------------where x in the number of rooms
When the price per room is increased by $3, the demand function will be;
p(x)=$63x
Maintenance per room after price increase will be;
p(x)=$16x
This means: $63x -$60x=$16x
3*80 p(x)=16*80
p(x)=(16*80)/(3*80) =5.33
Due to price increase the number of rooms occupied reduced by 5 rooms to 75 rooms. Because of unoccupied rooms bringing no revenue the maintenance cost increased. The demand for room decreased.
