100% + 70% = 170%
JeanRoshel =
170100 =
1710 Combined salaries at first
= 17 u + 10 u
= 27 u
Decrease in the combined salaries
= 80% x 27 u
=
80100 x 27 u
= 21.6 u
Combined salaries in the end
= 27 u + 21.6 u
= 5.4 u
5.4 u = 2484
1 u = 2484 ÷ 5.4 = 460
Jean's salary before the decrease
= 17 u
= 17 x 460
= $7820
Answer: $7820
