100% - 30% = 70%
IreneWendy =
70100 =
710 Combined salaries at first
= 7 u + 10 u
= 17 u
Decrease in the combined salaries
= 20% x 17 u
=
20100 x 17 u
= 3.4 u
Combined salaries in the end
= 17 u + 3.4 u
= 13.6 u
13.6 u = 5032
1 u = 5032 ÷ 13.6 = 370
Wendy's salary before the decrease
= 10 u
= 10 x 370
= $3700
Answer: $3700
