100% + 20% = 120%
BarbaraFanny =
120100 =
65 Combined salaries at first
= 6 u + 5 u
= 11 u
Decrease in the combined salaries
= 30% x 11 u
=
30100 x 11 u
= 3.3 u
Combined salaries in the end
= 11 u + 3.3 u
= 7.7 u
7.7 u = 3003
1 u = 3003 ÷ 7.7 = 390
Barbara's salary before the decrease
= 6 u
= 6 x 390
= $2340
Answer: $2340
