100% of Adam's original income = $200
1% of Adam's original income
= 200 ÷ 100
= $2
100% - 40% = 60%
60% of Adam's original income
= 60 x 2
= $120
60% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $120
1 u of Adam's new income
= 120 ÷ 100
= $1.20
100 u - 30 u = 70 u
70 u of Adam's new income
= 70 x 1.20
= $84
Adam's latest income = $84
Answer(s): $84
