100% of Adam's original income = $100
1% of Adam's original income = 100 ÷ 100 = $1
100% + 10% = 110%
110% of Adam's original income = 110 x 1 = $110
100% of Adam's new income = $110
1% of Adam's new income = 110 ÷ 100 = $1.10
100% + 10% = 110%
110% of Adam's new income = 110 x 1.10 = $121
Adam's latest income = $121
Answer(s): $121
