100% - 80% = 20%
JeanAbi =
20100 =
15 Combined salaries at first
= 1 u + 5 u
= 6 u
Increase in the combined salaries
= 20% x 6 u
=
20100 x 6 u
= 1.2 u
Combined salaries in the end
= 6 u + 1.2 u
= 7.2 u
7.2 u = 2808
1 u = 2808 ÷ 7.2 = 390
Abi's salary before the increase
= 5 u
= 5 x 390
= $1950
Answer: $1950
