New income after it was decreased by 20%
= 100% - 20%
= 80%
Decrease in savings
= 20% x 5%
=
20100 x 5%
= 1%
New savings in percentage
= 5% - 1%
= 4%
4% of the original income = 200
1% of the original income = 200 ÷ 4 = 50
100% of the original income = 10 x 50 = 5000
Jack's original income = $5000
Answer(s): $5000
