Question 1196916
.
A 650 room hotel in Orlando is filled to capacity every night when the room price is 90 per night. 
For every $5 dollar increase in price , 10 fewer rooms are filled. 
Find a linear formula for the number of rooms demanded, N, as a function of price p.
~~~~~~~~~~~~~~~~~


<pre>
We know that the formula is linear, and we know that the slope is this negative ratio

    m = {{{(-10)/5}}} = -2, 


which means that 2 rooms become vacant for each $1 increase in price.


Therefore, the formula for N(p) is  N{p) = 650 - 2p.    <U>ANSWER</U>


The formula really describes that 10 rooms become vacant as the price increase by $5.
