100% of Adam's original income = $300
1% of Adam's original income
= 300 ÷ 100
= $3
100% + 20% = 120%
120% of Adam's original income
= 120 x 3
= $360
120% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 360
1 u of Adam's new income
= 360 ÷ 100
= $3.60
100 u - 40 u = 60 u
60 u of Adam's new income
= 60 x 3.60
= $216
Adam's latest income = $216
Answer(s): $216
