100% + 60% = 160%
ShannonSarah =
160100 =
85 Combined salaries at first
= 8 u + 5 u
= 13 u
Decrease in the combined salaries
= 80% x 13 u
=
80100 x 13 u
= 10.4 u
Combined salaries in the end
= 13 u + 10.4 u
= 2.6 u
2.6 u = 754
1 u = 754 ÷ 2.6 = 290
Shannon's salary before the decrease
= 8 u
= 8 x 290
= $2320
Answer: $2320
