100% of Adam's original income = $500
1% of Adam's original income = 500 ÷ 100 = $5
100% + 30% = 130%
130% of Adam's original income = 130 x 5 = $650
100% of Adam's new income = $650
1% of Adam's new income = 650 ÷ 100 = $6.50
100% + 30% = 130%
130% of Adam's new income = 130 x 6.50 = $845
Adam's latest income = $845
Answer(s): $845
