100% - 50% = 50%
GabbyVictoria =
50100 =
12 Combined salaries at first
= 1 u + 2 u
= 3 u
Increase in the combined salaries
= 10% x 3 u
=
10100 x 3 u
= 0.3 u
Combined salaries in the end
= 3 u + 0.3 u
= 3.3 u
3.3 u = 1155
1 u = 1155 ÷ 3.3 = 350
Victoria's salary before the increase
= 2 u
= 2 x 350
= $700
Answer: $700
