100% + 30% = 130%
VanessaAbi =
130100 =
1310 Combined salaries at first
= 13 u + 10 u
= 23 u
Decrease in the combined salaries
= 40% x 23 u
=
40100 x 23 u
= 9.2 u
Combined salaries in the end
= 23 u + 9.2 u
= 13.8 u
13.8 u = 2760
1 u = 2760 ÷ 13.8 = 200
Vanessa's salary before the decrease
= 13 u
= 13 x 200
= $2600
Answer: $2600
