100% of Adam's original income = $200
1% of Adam's original income = 200 ÷ 100 = $2
100% + 40% = 140%
140% of Adam's original income = 140 x 2 = $280
100% of Adam's new income = $280
1% of Adam's new income = 280 ÷ 100 = $2.80
100% + 40% = 140%
140% of Adam's new income = 140 x 2.80 = $392
Adam's latest income = $392
Answer(s): $392
