100% of Adam's original income = $300
1% of Adam's original income = 300 ÷ 100 = $3
100% + 30% = 130%
130% of Adam's original income = 130 x 3 = $390
100% of Adam's new income = $390
1% of Adam's new income = 390 ÷ 100 = $3.90
100% + 30% = 130%
130% of Adam's new income = 130 x 3.90 = $507
Adam's latest income = $507
Answer(s): $507
