100% - 50% = 50%
JoelleEmily =
50100 =
12 Combined salaries at first
= 1 u + 2 u
= 3 u
Increase in the combined salaries
= 80% x 3 u
=
80100 x 3 u
= 2.4 u
Combined salaries in the end
= 3 u + 2.4 u
= 5.4 u
5.4 u = 1944
1 u = 1944 ÷ 5.4 = 360
Emily's salary before the increase
= 2 u
= 2 x 360
= $720
Answer: $720
