100% of Adam's original income = $300
1% of Adam's original income
= 300 ÷ 100
= $3
100% - 50% = 50%
50% of Adam's original income
= 50 x 3
= $150
50% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 150
1 u of Adam's new income
= 150 ÷ 100
= $1.50
100 u + 30 u = 130 u
130 u of Adam's new income
= 130 x 1.50
= $195
Adam's latest income = $195
Answer(s): $195
