100% + 10% = 110%
NicoleGem =
110100 =
1110 Combined salaries at first
= 11 u + 10 u
= 21 u
Increase in the combined salaries
= 60% x 21 u
=
60100 x 21 u
= 12.6 u
Combined salaries in the end
= 21 u + 12.6 u
= 33.6 u
33.6 u = 11760
1 u = 11760 ÷ 33.6 = 350
Nicole's salary before the increase
= 11 u
= 11 x 350
= $3850
Answer: $3850
