<PRE><B>Question 53359</B>
When a number of units are sold, the price of each unit (in dollars) is given by
P(x)= -x/2+75. Find the unit price when the following quantities are sold:2,7,9,11.
-----------
P(2)= -2/2 + 75 = $74
P(7)= -7/2 + 75 = $71.5
P(9)= -9/2 + 75 = $70.5
P(11)= -11/2 + 75 = $69.5
