A record company has determined that the cost of producing CDs is $\$ 0.06$ per CD plus $\$ 597.60$ per month in fixed costs. The record company sells each $C D$ for $\$ 15$. Step 1 of 4 : Find the revenue function.

Step 1 ：A record company has determined that the cost of producing CDs is $0.06 per CD plus $597.60 per month in fixed costs. The record company sells each CD for $15.

Step 2 ：The revenue function is the function that calculates the total income from selling a certain number of CDs. In this case, the company sells each CD for $15, so the revenue function would be the number of CDs sold multiplied by the price per CD.

Step 3 ：The revenue function is correctly defined as the price per CD times the number of CDs sold. This function will give us the total revenue for any given number of CDs sold.

Step 4 ：Final Answer: The revenue function is \(\boxed{R(n) = 15n}\), where \(n\) is the number of CDs sold.
