100% of Adam's original income = $1200
1% of Adam's original income
= 1200 ÷ 100
= $12
100% - 30% = 70%
70% of Adam's original income
= 70 x 12
= $840
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 840
1 u of Adam's new income
= 840 ÷ 100
= $8.40
100 u + 20 u = 120 u
120 u of Adam's new income
= 120 x 8.40
= $1008
Adam's latest income = $1008
Answer(s): $1008
