100% of Adam's original income = $1900
1% of Adam's original income
= 1900 ÷ 100
= $19
100% - 50% = 50%
50% of Adam's original income
= 50 x 19
= $950
50% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $950
1 u of Adam's new income
= 950 ÷ 100
= $9.50
100 u - 20 u = 80 u
80 u of Adam's new income
= 80 x 9.50
= $760
Adam's latest income = $760
Answer(s): $760
