a)   Increase in gross pay = 43 000 - 35 000 = $8 000
   Percent increase =  (100%) = 22.8571%
b)    Federal tax on $35 000 is 15% of $35000    $5 250
   Net pay after federal tax = 35000 - 5250 = 29 750
   Federal tax on 43 000
      On first $40970   $6145.50
      On excess 22% of 2030      446.60
         $6 592.10
   Net pay after federal tax = $43 000 - $6592.10 = $36 407.90
   Increase in net pay after federal tax = 36 407.90 - 29 750 = 6 657.90
   Percent increase =  (100%) = 22.3795%
