Answer:
Velma's share = 26.7%
Winnie's share = 33.3%
Zoe's share = 40%
Step-by-step explanation:
Let Velma's share be <em>v</em>.
Let Winnie's share be <em>w</em>.
Let Zoe's share be <em>z</em>.
Velma pays 25% more of Winnie's share
<em>v</em> = <em>w</em> + 25% of <em>w</em> = 125% of <em>w</em> = 1.25<em>w</em>
<em />
Zoe pays 50% more of Winnie's share
<em>v</em> = <em>w</em> + 50% of <em>w</em> = 150% of <em>w</em> = 1.5<em>w</em>
<em />
Total rent = <em>w</em> + 1.25<em>w </em>+ 1.5<em>w </em>= 3.75<em>w</em>
<em />
Velma's share =
Winnie's share =
Zoe's share =

The mean for one bet is
