100% of Adam's original income = $3600
1% of Adam's original income
= 3600 ÷ 100
= $36
100% - 40% = 60%
60% of Adam's original income
= 60 x 36
= $2160
60% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 2160
1 u of Adam's new income
= 2160 ÷ 100
= $21.60
100 u + 50 u = 150 u
150 u of Adam's new income
= 150 x 21.60
= $3240
Adam's latest income = $3240
Answer(s): $3240
