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

Substitute x=2,7,9,11 into the problem and solve for p like so:

When x=2

p=$74
When x=7

p=$71.50
When x=9

p=$70.50
When x=11

p=$69.50
