100% of Adam's original income = $3600
1% of Adam's original income
= 3600 ÷ 100
= $36
100% + 10% = 110%
110% of Adam's original income
= 110 x 36
= $3960
110% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 3960
1 u of Adam's new income
= 3960 ÷ 100
= $39.60
100 u - 40 u = 60 u
60 u of Adam's new income
= 60 x 39.60
= $2376
Adam's latest income = $2376
Answer(s): $2376
