dimulka [17.4K]

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

$1.20x$

Fixed cost is $8000.

Therefore, cost function is

$C(x)=1.20x+8000$

Selling price of each drink is $2.

Therefore, the revenue function is

$R(x)=2x$

Hence, the revenue function is

$R(x)=2x$
