100% of Adam's original income = $400
1% of Adam's original income = 400 ÷ 100 = $4
100% + 40% = 140%
140% of Adam's original income = 140 x 4 = $560
100% of Adam's new income = $560
1% of Adam's new income = 560 ÷ 100 = $5.60
100% + 40% = 140%
140% of Adam's new income = 140 x 5.60 = $784
Adam's latest income = $784
Answer(s): $784
