100% - 80% = 20%
FannyNicole =
20100 =
15 Combined salaries at first
= 1 u + 5 u
= 6 u
Decrease in the combined salaries
= 40% x 6 u
=
40100 x 6 u
= 2.4 u
Combined salaries in the end
= 6 u + 2.4 u
= 3.6 u
3.6 u = 1584
1 u = 1584 ÷ 3.6 = 440
Nicole's salary before the decrease
= 5 u
= 5 x 440
= $2200
Answer: $2200
