First, add $20 and $20 and $20 and $20 because of the one $20 bill and the two ten dollar bills.
Add the 10 quarters which is 2.50 and add 12 nickles 60 cents or .60 then add 2 pennies.
The answer is $83.12 cents.
Now divide that by 4 which is 20.78
So to answer your question: 20.78 is how much each charity would get.
