100% of Adam's original income = $900
1% of Adam's original income = 900 ÷ 100 = $9
100% + 10% = 110%
110% of Adam's original income = 110 x 9 = $990
100% of Adam's new income = $990
1% of Adam's new income = 990 ÷ 100 = $9.90
100% + 10% = 110%
110% of Adam's new income = 110 x 9.90 = $1089
Adam's latest income = $1089
Answer(s): $1089
