New salary 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 salary = 168
1% of the original salary = 168 ÷ 4 = 42
100% of the original salary = 10 x 42 = 4200
Howard's original salary = $4200
Answer(s): $4200
