Question

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

Answer 1

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.
