100% + 80% = 180%
JadeMin =
180100 =
95 Combined salaries at first
= 9 u + 5 u
= 14 u
Decrease in the combined salaries
= 20% x 14 u
=
20100 x 14 u
= 2.8 u
Combined salaries in the end
= 14 u + 2.8 u
= 11.2 u
11.2 u = 2800
1 u = 2800 ÷ 11.2 = 250
Jade's salary before the decrease
= 9 u
= 9 x 250
= $2250
Answer: $2250
