100% + 70% = 170%
PamelaGem =
170100 =
1710 Combined salaries at first
= 17 u + 10 u
= 27 u
Decrease in the combined salaries
= 50% x 27 u
=
50100 x 27 u
= 13.5 u
Combined salaries in the end
= 27 u + 13.5 u
= 13.5 u
13.5 u = 6750
1 u = 6750 ÷ 13.5 = 500
Pamela's salary before the decrease
= 17 u
= 17 x 500
= $8500
Answer: $8500
