100% + 30% = 130%
FionaLucy =
130100 =
1310 Combined salaries at first
= 13 u + 10 u
= 23 u
Increase in the combined salaries
= 70% x 23 u
=
70100 x 23 u
= 16.1 u
Combined salaries in the end
= 23 u + 16.1 u
= 39.1 u
39.1 u = 8993
1 u = 8993 ÷ 39.1 = 230
Fiona's salary before the increase
= 13 u
= 13 x 230
= $2990
Answer: $2990
