100% - 60% = 40%
ShannonEsther =
40100 =
25 Combined salaries at first
= 2 u + 5 u
= 7 u
Decrease in the combined salaries
= 20% x 7 u
=
20100 x 7 u
= 1.4 u
Combined salaries in the end
= 7 u + 1.4 u
= 5.6 u
5.6 u = 2688
1 u = 2688 ÷ 5.6 = 480
Esther's salary before the decrease
= 5 u
= 5 x 480
= $2400
Answer: $2400
