Question 1030439
You lost {{{80(0.2)=16}}}.
You give away {{{80(0.5)=40}}}.
So all totaled you don't have 56 of the original 80.
That leaves you with,
{{{80-56=24}}}
.
.
.
If you gave away 50% of what you had after you lost the first 16.
Then you gave away,
{{{(80-16)*0.5=64*0.5=32}}}
So then you would have,
{{{80-16-32= 32}}}
