Question
The manager of a large apartment
complex knows from experience that
100 units will be occupied if the rent is

month. A market
survey suggests that, on the average,
one additional unit will remain vacant
for each 7 dollar increase in rent.
Similarly, one additional unit will be
occupied for each 7 dollar decrease in
rent.
(a) If æ is the number of units rented,
and p is the rent per unit in dollars,
what is the price-demand equation
(assuming it is linear)?
P
(b) What is the monthly revenue
function for the manager?
(Hint: Revenue is the product of the
price per item and the number of
items.)
R(x) =
