Given January income = 12.43 million dollars = $12430000
Disposable income means income after taxes. So in February there is extra deduction of 0.2% for taxes.
If we convert that percentage to decimal = [tex]\frac{0.2}{100} = 0.002[/tex]
Reduced amount = 12430000*0.002 = $24860
Hence February income = 12430000 - 24860 = $12405140= 12.41 million dollars
