100% of Adam's original income = $200
1% of Adam's original income
= 200 ÷ 100
= $2
100% - 20% = 80%
80% of Adam's original income
= 80 x 2
= $160
80% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 160
1 u of Adam's new income
= 160 ÷ 100
= $1.60
100 u + 10 u = 110 u
110 u of Adam's new income
= 110 x 1.60
= $176
Adam's latest income = $176
Answer(s): $176
