100% of Adam's original income = $300
1% of Adam's original income
= 300 ÷ 100
= $3
100% - 10% = 90%
90% of Adam's original income
= 90 x 3
= $270
90% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = 270
1 u of Adam's new income
= 270 ÷ 100
= $2.70
100 u + 50 u = 150 u
150 u of Adam's new income
= 150 x 2.70
= $405
Adam's latest income = $405
Answer(s): $405
