100% of Adam's original income = $3400
1% of Adam's original income
= 3400 ÷ 100
= $34
100% - 30% = 70%
70% of Adam's original income
= 70 x 34
= $2380
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $2380
1 u of Adam's new income
= 2380 ÷ 100
= $23.80
100 u - 20 u = 80 u
80 u of Adam's new income
= 80 x 23.80
= $1904
Adam's latest income = $1904
Answer(s): $1904
