100% of Adam's original income = $300
1% of Adam's original income = 300 ÷ 100 = $3
100% + 40% = 140%
140% of Adam's original income = 140 x 3 = $420
100% of Adam's new income = $420
1% of Adam's new income = 420 ÷ 100 = $4.20
100% + 40% = 140%
140% of Adam's new income = 140 x 4.20 = $588
Adam's latest income = $588
Answer(s): $588
