New income after it was increased by 30%
= 100% + 30%
= 130%
Increase in savings
= 30% x 20%
=
30100 x 20%
= 6%
New savings in percentage
= 20% + 6%
= 26%
26% of the original income = 182
1% of the original income = 182 ÷ 26 = 7
100% of the original income = 100 x 7 = 700
Charlie's original income = $700
Answer(s): $700
