100% of Adam's original income = $4100
1% of Adam's original income
= 4100 ÷ 100
= $41
100% - 30% = 70%
70% of Adam's original income
= 70 x 41
= $2870
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 2870
1 u of Adam's new income
= 2870 ÷ 100
= $28.70
100 u + 40 u = 140 u
140 u of Adam's new income
= 140 x 28.70
= $4018
Adam's latest income = $4018
Answer(s): $4018
