100% + 30% = 130%
PamelaElyse =
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 = 6440
1 u = 6440 ÷ 32.2 = 200
Pamela's salary before the increase
= 13 u
= 13 x 200
= $2600
Answer: $2600
