In a certain state, people with an income under $15K pay a minimum income tax plus a % of the amount over $12,750.00.
The table below shows the income, x, and the taxes paid; y for several people.
Using a a linear model, what is the additional % people pay in this state?
Income $ Taxes Pad $
Possible answers are 6%, 7%, 8%, 9%
x (15,000 - 12,750) = 922.50
x (25,000 - 12,750) = 1622.50
Solve for x in any one of the four situations.
