100% of Adam's original income = $400
1% of Adam's original income = 400 ÷ 100 = $4
100% + 30% = 130%
130% of Adam's original income = 130 x 4 = $520
100% of Adam's new income = $520
1% of Adam's new income = 520 ÷ 100 = $5.20
100% + 30% = 130%
130% of Adam's new income = 130 x 5.20 = $676
Adam's latest income = $676
Answer(s): $676
