how do i solve this?
When x number of units are sold, the price of each unit (in dollars) is given by . Find the unit price when the following quantities are sold: 2,7,9,11.
You seem to have omitted an equation after the word "by"
the equation is :
p= x/2 + 75
If p = x/2 + 75 ,
then when x (which is the number sold) = 2,
p (which is the price per unit) = 75  2/2 = $74
Do the others the same way.
When x = 11, the price is 75  11/2 dollars = $69.50
