MarionFanny =
160100 =
85 Combined salaries at first
= 8 u + 5 u
= 13 u
Decrease in the combined salaries
= 50% x 13 u
=
50100 x 13 u
= 6.5 u
Combined salaries in the end
= 13 u + 6.5 u
= 6.5 u
6.5 u = 3055
1 u = 3055 ÷ 6.5 = 470
Marion's salary before the decrease
= 8 u
= 8 x 470
= $3760
Answer: $3760
