100% - 70% = 30%
VictoriaShannon =
30100 =
310 Combined salaries at first
= 3 u + 10 u
= 13 u
Increase in the combined salaries
= 20% x 13 u
=
20100 x 13 u
= 2.6 u
Combined salaries in the end
= 13 u + 2.6 u
= 15.6 u
15.6 u = 4836
1 u = 4836 ÷ 15.6 = 310
Shannon's salary before the increase
= 10 u
= 10 x 310
= $3100
Answer: $3100
