New income after it was decreased by 40%
= 100% - 40%
= 60%
Decrease in savings
= 40% x 25%
=
40100 x 25%
= 10%
New savings in percentage
= 25% - 10%
= 15%
15% of the original income = 120
1% of the original income = 120 ÷ 15 = 8
100% of the original income = 10 x 8 = 800
Elijah's original income = $800
Answer(s): $800
