100% - 30% = 70%
ElyseCindy =
70100 =
710 Combined salaries at first
= 7 u + 10 u
= 17 u
Increase in the combined salaries
= 70% x 17 u
=
70100 x 17 u
= 11.9 u
Combined salaries in the end
= 17 u + 11.9 u
= 28.9 u
28.9 u = 10693
1 u = 10693 ÷ 28.9 = 370
Cindy's salary before the increase
= 10 u
= 10 x 370
= $3700
Answer: $3700
