100% of Adam's original income = $2800
1% of Adam's original income
= 2800 ÷ 100
= $28
100% - 10% = 90%
90% of Adam's original income
= 90 x 28
= $2520
90% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 2520
1 u of Adam's new income
= 2520 ÷ 100
= $25.20
100 u + 20 u = 120 u
120 u of Adam's new income
= 120 x 25.20
= $3024
Adam's latest income = $3024
Answer(s): $3024
