100% - 30% = 70%
JeanGabby =
70100 =
710 Combined salaries at first
= 7 u + 10 u
= 17 u
Increase in the combined salaries
= 80% x 17 u
=
80100 x 17 u
= 13.6 u
Combined salaries in the end
= 17 u + 13.6 u
= 30.6 u
30.6 u = 14076
1 u = 14076 ÷ 30.6 = 460
Gabby's salary before the increase
= 10 u
= 10 x 460
= $4600
Answer: $4600
