DanaPamela =
160100 =
85 Combined salaries at first
= 8 u + 5 u
= 13 u
Decrease in the combined salaries
= 20% x 13 u
=
20100 x 13 u
= 2.6 u
Combined salaries in the end
= 13 u + 2.6 u
= 10.4 u
10.4 u = 3640
1 u = 3640 ÷ 10.4 = 350
Dana's salary before the decrease
= 8 u
= 8 x 350
= $2800
Answer: $2800
