100% of Adam's original income = $2700
1% of Adam's original income
= 2700 ÷ 100
= $27
100% - 40% = 60%
60% of Adam's original income
= 60 x 27
= $1620
60% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 1620
1 u of Adam's new income
= 1620 ÷ 100
= $16.20
100 u + 50 u = 150 u
150 u of Adam's new income
= 150 x 16.20
= $2430
Adam's latest income = $2430
Answer(s): $2430
