100% + 80% = 180%
IvoryNatalie =
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 = 3808
1 u = 3808 ÷ 11.2 = 340
Ivory's salary before the decrease
= 9 u
= 9 x 340
= $3060
Answer: $3060
