Practice Question number 3: Karl (end of notes)

Hi,

In the answer workings to practice question 3, there is:

41,700 x 20% = 8,340
95,300 x 40% = 38,120

2,000 @ 0% = 0
15,000 @ 33.75% = 5,062
13,000 @ 39.35 % = 5,116

Income Tax Liability = 56,288

Is this a typo? Because after adding these numbers up I have 56,638.

Or have a missed something?

Thank you for the help.

Charley
