100% - 20% = 80%
DianaJane =
80100 =
45 Combined salaries at first
= 4 u + 5 u
= 9 u
Increase in the combined salaries
= 80% x 9 u
=
80100 x 9 u
= 7.2 u
Combined salaries in the end
= 9 u + 7.2 u
= 16.2 u
16.2 u = 7614
1 u = 7614 ÷ 16.2 = 470
Jane's salary before the increase
= 5 u
= 5 x 470
= $2350
Answer: $2350
