Let X be the number of energy drinks sold. 
The manufacturer of an energy drink spends $1.20 to make each drink and sells them for two dollars the manufacturer also has fixed cost each month of $8000.
The manufacturing cost for X energy drinks is

Fixed cost is $8000.
Therefore, cost function is

Selling price of each drink is $2. 
Therefore, the revenue function is

Hence, the revenue function is

Step-by-step explanation:
Remember for division questions to use Keep, Change, Flip. You will Keep the first term the same. Change the divide to times. And Flip the second term (turn it upside down, in math this is called the reciprocal)
Also, you need to know when you you get to the part where everything is times, then you times: top×top, and bottom×bottom. 
Once everything is times, you can rearrange the order and cancel (cancel is not really the mathy thing happening, you are dividing--- 
x/x is 1 and y/y is 1, 
10/5 is 2, 6/3 is 2) See image.
