100% of Adam's original income = $3700
1% of Adam's original income
= 3700 ÷ 100
= $37
100% - 10% = 90%
90% of Adam's original income
= 90 x 37
= $3330
90% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 3330
1 u of Adam's new income
= 3330 ÷ 100
= $33.30
100 u + 30 u = 130 u
130 u of Adam's new income
= 130 x 33.30
= $4329
Adam's latest income = $4329
Answer(s): $4329
