100% of Adam's original income = $400
1% of Adam's original income = 400 ÷ 100 = $4
100% + 10% = 110%
110% of Adam's original income = 110 x 4 = $440
100% of Adam's new income = $440
1% of Adam's new income = 440 ÷ 100 = $4.40
100% + 10% = 110%
110% of Adam's new income = 110 x 4.40 = $484
Adam's latest income = $484
Answer(s): $484
