Our vending machine is in a great spot, it's packed with yummy snacks, and it's working smoothly. Now comes the fun part: earning coins! This is where we start to see the fruits of our labor. And it's not just about collecting money, but also about making our vending machine business bigger and better.

First things first, we need to keep track of our earnings. Picture a big jar where you save all your coins. At the end of each day or week, you can count how much you've earned. You might even want to keep a notebook to write down how much you make. This is a great way to see how well your business is doing.

Remember, we have to subtract the money we spent on snacks and drinks, and any costs for fixing the machine. The money that's left over is our profit. That's the money we get to keep!
