100% - 10% = 90%
NicoleEva =
90100 =
910 Combined salaries at first
= 9 u + 10 u
= 19 u
Increase in the combined salaries
= 60% x 19 u
=
60100 x 19 u
= 11.4 u
Combined salaries in the end
= 19 u + 11.4 u
= 30.4 u
30.4 u = 15200
1 u = 15200 ÷ 30.4 = 500
Eva's salary before the increase
= 10 u
= 10 x 500
= $5000
Answer: $5000
