100% - 40% = 60%
EmilyJen =
60100 =
35 Combined salaries at first
= 3 u + 5 u
= 8 u
Increase in the combined salaries
= 70% x 8 u
=
70100 x 8 u
= 5.6 u
Combined salaries in the end
= 8 u + 5.6 u
= 13.6 u
13.6 u = 4352
1 u = 4352 ÷ 13.6 = 320
Jen's salary before the increase
= 5 u
= 5 x 320
= $1600
Answer: $1600
