100% of Adam's original income = $3200
1% of Adam's original income
= 3200 ÷ 100
= $32
100% - 10% = 90%
90% of Adam's original income
= 90 x 32
= $2880
90% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $2880
1 u of Adam's new income
= 2880 ÷ 100
= $28.80
100 u - 15 u = 85 u
85 u of Adam's new income
= 85 x 28.80
= $2448
Adam's latest income = $2448
Answer(s): $2448
