100% - 80% = 20%
AnnaEmily =
20100 =
15 Combined salaries at first
= 1 u + 5 u
= 6 u
Increase in the combined salaries
= 30% x 6 u
=
30100 x 6 u
= 1.8 u
Combined salaries in the end
= 6 u + 1.8 u
= 7.8 u
7.8 u = 3198
1 u = 3198 ÷ 7.8 = 410
Emily's salary before the increase
= 5 u
= 5 x 410
= $2050
Answer: $2050
