Question 689918: Two proposed tax bills. The first states a homeowner will pay 1900$ plus 4% of their assessed homes value in taxes. The second bill proposes a 500$ payment and 9% of their homes value in taxes. What price range of the home assessment would make the first deal a better deal for the homeowner?
This is what I have came up with: 1900+0.04*x>500+0.09*x Then I should subtract 0.04x from both sides. Simplify it to 1900>500+0.05x. Then subtract 500 and simplify to get 1400>0.05x... then I divide by 0.05 to get 28000... is this right? A home greater than 28000 would be the best deal?
