100% of Adam's original income = $3200
1% of Adam's original income
= 3200 ÷ 100
= $32
100% - 30% = 70%
70% of Adam's original income
= 70 x 32
= $2240
70% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 2240
1 u of Adam's new income
= 2240 ÷ 100
= $22.40
100 u + 10 u = 110 u
110 u of Adam's new income
= 110 x 22.40
= $2464
Adam's latest income = $2464
Answer(s): $2464
