100% of Adam's original income = $2600
1% of Adam's original income
= 2600 ÷ 100
= $26
100% - 40% = 60%
60% of Adam's original income
= 60 x 26
= $1560
60% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 1560
1 u of Adam's new income
= 1560 ÷ 100
= $15.60
100 u + 30 u = 130 u
130 u of Adam's new income
= 130 x 15.60
= $2028
Adam's latest income = $2028
Answer(s): $2028
