100% - 10% = 90%
JaslynVanessa =
90100 =
910 Combined salaries at first
= 9 u + 10 u
= 19 u
Decrease in the combined salaries
= 20% x 19 u
=
20100 x 19 u
= 3.8 u
Combined salaries in the end
= 19 u + 3.8 u
= 15.2 u
15.2 u = 3040
1 u = 3040 ÷ 15.2 = 200
Vanessa's salary before the decrease
= 10 u
= 10 x 200
= $2000
Answer: $2000
