100% - 70% = 30%
FannyDana =
30100 =
310 Combined salaries at first
= 3 u + 10 u
= 13 u
Increase in the combined salaries
= 30% x 13 u
=
30100 x 13 u
= 3.9 u
Combined salaries in the end
= 13 u + 3.9 u
= 16.9 u
16.9 u = 4901
1 u = 4901 ÷ 16.9 = 290
Dana's salary before the increase
= 10 u
= 10 x 290
= $2900
Answer: $2900
