100% of Adam's original income = $300
1% of Adam's original income = 300 ÷ 100 = $3
100% + 20% = 120%
120% of Adam's original income = 120 x 3 = $360
100% of Adam's new income = $360
1% of Adam's new income = 360 ÷ 100 = $3.60
100% + 20% = 120%
120% of Adam's new income = 120 x 3.60 = $432
Adam's latest income = $432
Answer(s): $432
