100% of Adam's original income = $1200
1% of Adam's original income
= 1200 ÷ 100
= $12
100% - 20% = 80%
80% of Adam's original income
= 80 x 12
= $960
80% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 960
1 u of Adam's new income
= 960 ÷ 100
= $9.60
100 u + 10 u = 110 u
110 u of Adam's new income
= 110 x 9.60
= $1056
Adam's latest income = $1056
Answer(s): $1056
