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
100 u of Adam's new income = $150
1 u of Adam's new income = 150 ÷ 100 = $1.50
100 u + 50 u = 150 u
150% of Adam's new income = 150 x 1.50 = $225
Adam's latest income = $225
Answer(s): $225
