New income after it was decreased by 40%
= 100% - 40%
= 60%
Decrease in savings
= 40% x 5%
=
40100 x 5%
= 2%
New savings in percentage
= 5% - 2%
= 3%
3% of the original income = 132
1% of the original income = 132 ÷ 3 = 44
100% of the original income = 10 x 44 = 4400
David's original income = $4400
Answer(s): $4400
