how much money did Freya have at the start ???
Let Freya's money at the start = F
Call the amount that Jess originally has = 1/2 F
So....Jess gives Freya (2/5)(1/2)F
And Kim started with 24 / (1/4) = £96 ....so she gave Freya £72
So at the end, Freya has
F + (2/5)(1/2)F + 72 = 168 subtract 72 from each side
F + (1/5)F = 96
(6/5)F = 96
F = 96(5/6) = £80
So...Freya had £80 at the start
