AnnaElyse =
170100 =
1710 Combined salaries at first
= 17 u + 10 u
= 27 u
Increase in the combined salaries
= 30% x 27 u
=
30100 x 27 u
= 8.1 u
Combined salaries in the end
= 27 u + 8.1 u
= 35.1 u
35.1 u = 12285
1 u = 12285 ÷ 35.1 = 350
Anna's salary before the increase
= 17 u
= 17 x 350
= $5950
Answer: $5950
