<PRE><B>Question 1055163</B>
You spend $28 on ingredients to make cookies. You charge $4 per container of cookies. How many containers do you need to sell to earn $20 in profit?
--------------
Cost:: 28
Revenue:: 4x
-----
Profit = Revenue - Cost
P(x) = 4x - 28
------
Solve:: 4x-28 = 20
4x = 48
x = 12 (# of containers needed)
---------
