Lacy is a single taxpayer with $50,000 of taxable income. Please determine her tax liability assuming that: a. all of her income relates to salary received from her employer. b. the $50,000 of taxable income includes $5,000 of qualified dividend income. Why do you think dividend income and long term capital gain income is taxed at favorable tax rates (i.e., tax rates that are lower than what ordinarily applies)
