100% of Adam's original income = $1800
1% of Adam's original income
= 1800 ÷ 100
= $18
100% - 25% = 75%
75% of Adam's original income
= 75 x 18
= $1350
75% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $1350
1 u of Adam's new income
= 1350 ÷ 100
= $13.50
100 u - 30 u = 70 u
70 u of Adam's new income
= 70 x 13.50
= $945
Adam's latest income = $945
Answer(s): $945
