100% - 60% = 40%
SarahPamela =
40100 =
25 Combined salaries at first
= 2 u + 5 u
= 7 u
Decrease in the combined salaries
= 40% x 7 u
=
40100 x 7 u
= 2.8 u
Combined salaries in the end
= 7 u + 2.8 u
= 4.2 u
4.2 u = 1344
1 u = 1344 ÷ 4.2 = 320
Pamela's salary before the decrease
= 5 u
= 5 x 320
= $1600
Answer: $1600
