100% - 30% = 70%
XandraJaslyn =
70100 =
710 Combined salaries at first
= 7 u + 10 u
= 17 u
Increase in the combined salaries
= 10% x 17 u
=
10100 x 17 u
= 1.7 u
Combined salaries in the end
= 17 u + 1.7 u
= 18.7 u
18.7 u = 5797
1 u = 5797 ÷ 18.7 = 310
Jaslyn's salary before the increase
= 10 u
= 10 x 310
= $3100
Answer: $3100
