100% of Adam's original income = $1300
1% of Adam's original income
= 1300 ÷ 100
= $13
100% - 20% = 80%
80% of Adam's original income
= 80 x 13
= $1040
80% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 1040
1 u of Adam's new income
= 1040 ÷ 100
= $10.40
100 u + 50 u = 150 u
150 u of Adam's new income
= 150 x 10.40
= $1560
Adam's latest income = $1560
Answer(s): $1560
