You can put this solution on YOUR website!
You lost 80%280.2%29=16.
You give away 80%280.5%29=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,
%2880-16%29%2A0.5=64%2A0.5=32
So then you would have,
80-16-32=+32
