You work for 6.5 hours at a rate of $11.50/ hour. you but dinner that cost $12, and give a 20% tip. how much money are you left with?

The most important part of the problem lies in the fact that the hours have to be converted to minutes before starting to solve the problem.

1 hour = 60 minutes

6 and half hours = (6 * 60) + 30 minutes

= 360 + 30

= 390 minutes

So the payment for 390 minutes is = 78 dollars

Then

The payment for 60 minutes = (78/390) * 60

= 2 * 6 dollars

= 12 dollars

So the rate of pay given is $12 per hour. I hope the procedure is easy enough for you to understand. You can always use this method for solving similar type of problems.
