Metro City's Non-Resident Earnings tax is $6.50$ per thousand dollars of earnings. However, if you earn under $10,000,$ you may subtract $3000$ from your earnings; if between 10,000 and 20,000, you may subtract $2000 ;$ and if between 20,000 and $30,000,$ you may subtract 1000 . So, for example, on 26,000 earnings, you may subtract 1000 and pay tax on 25,000 . Your tax is (25)(6.5)= 162.50 .$ Express the tax $ ,x as a function of x in thousands. Plot the graph. Would you rather earn 19,999(x=19.999) or 20,001 (x=20.001) ?
