Total Money he made is equal to sum of Money made in tips and Hourly rate multiplied by number of hours he worked.
framing in equation form we get;

Hence the equation to determine the number of hours we worked is
.
On Solving equation we get;
First we will subtract both side by 45 we get;

Dividing both side by 3 we get;

Hence the waiter has worked for 5 hours.
