100% + 30% = 130%
GabbyVanessa =
130100 =
1310 Combined salaries at first
= 13 u + 10 u
= 23 u
Increase in the combined salaries
= 40% x 23 u
=
40100 x 23 u
= 9.2 u
Combined salaries in the end
= 23 u + 9.2 u
= 32.2 u
32.2 u = 13202
1 u = 13202 ÷ 32.2 = 410
Gabby's salary before the increase
= 13 u
= 13 x 410
= $5330
Answer: $5330
