100% of Adam's original income = $1800
1% of Adam's original income
= 1800 ÷ 100
= $18
100% - 30% = 70%
70% of Adam's original income
= 70 x 18
= $1260
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $1260
1 u of Adam's new income
= 1260 ÷ 100
= $12.60
100 u - 40 u = 60 u
60 u of Adam's new income
= 60 x 12.60
= $756
Adam's latest income = $756
Answer(s): $756
