If they each kept the same amount of the $50 prize, then we divide $50
by 2 people, giving each of them $25 winnings. Your question is then a
little confusing because it could be answered in two ways. Did they
each keep $20.75 out of their $25 winnings, or did the two of them keep
$20.75 in a combined total? Please read your question again to see
which might be the case. I'm answering on the assumption that they each
kept $20.75.
STEP 1: divide total prize money by 2
= $50 ÷ 2 = $25 each won
STEP 2: If they each kept $20.75
= $25 won - $20.75 each kept = $4.25 each gave away
STEP 3: multiply amount given away by 2 people = $4.25 * 2 people = $8.50 total given away
