Doreen has started a part time business making and selling bird feeders. her equipment cost $75. If she makes a profit of $6 on each bird feeder, how many must Doreen sell to make a total profit of more than $135?
--------------------------
Let number of feeders sold = "x"
Profit from these x units = 6x dollars
INEQUALITY:
6x >= 75+135
6x>= 210
x>=70/2=35
Doreen must sell at least 35 bird feeders.
