100% - 40% = 60%
JaslynJulie =

35 Combined salaries at first
= 3 u + 5 u
= 8 u
Increase in the combined salaries
= 20% x 8 u
=
20100 x 8 u
= 1.6 u
Combined salaries in the end
= 8 u + 1.6 u
= 9.6 u
9.6 u = 3936
1 u = 3936 ÷ 9.6 = 410
Julie's salary before the increase
= 5 u
= 5 x 410
= $2050
Answer: $2050
