Mrs. bull spilled coffee on her computer during the first week of school! the total cost after tax to repair is represented by 0.09(75h)+75h, where h represents the number of hours it takes to repair her computer. what part of the expression represents the amount of tax mrs. bull has to pay? explain

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.
