A DJ working a wedding charges a flat fee of $200 plus $55 per hour. Find the cost of the DJ when she works 5 hours.

Step-by-step explanation:

First, as a constant we add $200 because never mind how long she works, she'll always get $200. After that, we add the multiplied result of $55 times 5 hours. And, that's the final result. After 5 hours, she'll get $475.
