New salary after it was decreased by 20%
= 100% - 20%
= 80%
Decrease in savings
= 20% x 15%
=
20100 x 15%
= 3%
New savings in percentage
= 15% - 3%
= 12%
12% of the original salary = 120
1% of the original salary = 120 ÷ 12 = 10
100% of the original salary = 10 x 10 = 1000
Elijah's original salary = $1000
Answer(s): $1000
