There is an income tax on the planet Bozone. Both annual income, x , and income tax, T ( x ) , are measured in the local currency, the Bozat ( B η ). If the annual income x < 1000 , then the income tax is 10% of the income: T ( x ) = 0.10 x . If annual income x ≥ 1000 , then the income tax is 15% of the income: T ( x ) = 0.15 x . a. The equation for the income tax on income between B η 0 and B η 1000 is of the form T ( x ) = m x + b . Find the values of m and b .
