From the given expression it seems that the hourly rate is 75 and the tax is 9%

So, the total cost is 75h + 9% of 75h = 75h + (9/100) (75h)

                                                            = 75h + (0.09)75h

                                                            = (0.09)75h + 75h

So, the amount of tax that Mrs. Bull has to pay is (0.09)75h = 6.75.
