Harri is the manager of a pet store. For his birthday, his employees decided to surprise him with a birthday cake. The cake cost \(\$65.40\) and everyone agreed to split the cost evenly. However, when it came time to collect the money, three of the employees were nowhere to be found. This meant that everyone else had to pay an additional \(\$1.09\) to cover the cost of the cake. How many employees does Harri have at the pet store?
