Answer: a) $3,304.75 b) $23,510.75Step-by-step explanation:To use a tax table like this, you find the line applicable to the taxable income, then perform the calculation described on that line.a)The taxable income of $25000 is over $7825, but less than $31850. That means the second line of the table is used. It tells you the tax is $782.50 plus 15% of the amount over $7825. You find the amount over $7825 by subtracting $7825 from $25000. tax = $728.50 +0.15×(25000 -7825) = $728.50 +0.15×17,175 tax = $728.50 +2576.25 = $3,304.75 . . . . tax on $25,000__b)For a taxable income of $105,000, the fourth line of the table is used. That tells you the tax computation is ... tax = $15,698.75 +0.28×(105,000 -77,100) tax = $23,510.75 . . . . tax on $105,000
