I don't actually know the answer because i'm working on it now, but what i can help you with is, compare the money that Trinity made and Jason made! I hope this helps a little bit!
If he is making 10 dollars an hour then to represent the raise, you would multiply 10 by 5% and add the result onto 10 to get how much he will be making per hour. In this case, 10 x 1.05 would be the equation.
