100 u |
$1680 |

$1260 |
100% of Adam's original income = $2800
1% of Adam's original income
= 2800 ÷ 100
= $28
100% - 40% = 60%
60% of Adam's original income
= 60 x 28
= $1680
60% of Adam's original income = 100 u of Adam's new income
100 u of Adam's new income = $1680
1 u of Adam's new income
= 1680 ÷ 100
= $16.80
100 u - 25 u = 75 u
75 u of Adam's new income
= 75 x 16.80
= $1260
Adam's latest income = $1260
Answer(s): $1260
