Answer:

#16#

Explanation:

First you convert #80%# into a decimal which is #.80# then you multiply it by #20#.

#.80xx20=16#

We multiply it by #20# because that's our total and by #.80# because that's the amount that we got correct. Had it been #100%# then that would mean we got every question right.
