100% of Adam's original income = $2200
1% of Adam's original income
= 2200 ÷ 100
= $22
100% - 30% = 70%
70% of Adam's original income
= 70 x 22
= $1540
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $1540
1 u of Adam's new income
= 1540 ÷ 100
= $15.40
100 u - 40 u = 60 u
60 u of Adam's new income
= 60 x 15.40
= $924
Adam's latest income = $924
Answer(s): $924
