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 .
