100% of Adam's original income = $2400
1% of Adam's original income
= 2400 ÷ 100
= $24
100% - 30% = 70%
70% of Adam's original income
= 70 x 24
= $1680
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 1680
1 u of Adam's new income
= 1680 ÷ 100
= $16.80
100 u + 40 u = 140 u
140 u of Adam's new income
= 140 x 16.80
= $2352
Adam's latest income = $2352
Answer(s): $2352
