100% + 70% = 170%
ElyseIrene =
170100 =
1710 Combined salaries at first
= 17 u + 10 u
= 27 u
Increase in the combined salaries
= 80% x 27 u
=
80100 x 27 u
= 21.6 u
Combined salaries in the end
= 27 u + 21.6 u
= 48.6 u
48.6 u = 17010
1 u = 17010 ÷ 48.6 = 350
Elyse's salary before the increase
= 17 u
= 17 x 350
= $5950
Answer: $5950
