100% - 20% = 80%
EstherEmma =
80100 =
45 Combined salaries at first
= 4 u + 5 u
= 9 u
Decrease in the combined salaries
= 40% x 9 u
=
40100 x 9 u
= 3.6 u
Combined salaries in the end
= 9 u + 3.6 u
= 5.4 u
5.4 u = 1458
1 u = 1458 ÷ 5.4 = 270
Emma's salary before the decrease
= 5 u
= 5 x 270
= $1350
Answer: $1350
