Maribel's city imposes a tax that is 40% of the state tax she pays. Her taxable income is $198.50 per week. Her state imposes tax at a rate of 5%. How much state and local tax is withheld from her weekly pay?

198.5 * 0.05 = 9.925 >> state tax
9.925 * 0.4 = 3.97 >> city tax
9.925 + 3.97 = 13.895 = 13.90 >> total tax
