100% of Adam's original income = $400
1% of Adam's original income
= 400 ÷ 100
= $4
100% - 40% = 60%
60% of Adam's original income
= 60 x 4
= $240
60% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 240
1 u of Adam's new income
= 240 ÷ 100
= $2.40
100 u + 10 u = 110 u
110 u of Adam's new income
= 110 x 2.40
= $264
Adam's latest income = $264
Answer(s): $264
