Percentage of school taxes that need to be paid for a local district = 2.5%
Amount of income made by the Smith Household per year= $80000
Amount of money paid by the Smith's per year as school taxes = (2.5/100) * 80000
= 2.5 * 800
= 2000 dollars
So $2000 is the amount that the Smith's household needs to pay as school taxes every year. I hope the procedure needs no further clarification and the answer is what you were looking for.
