All you need to do here is add all the answers up and divide them by the number of how much answers there where. Example: #3: 2.5+4.6+6.7+4.8=18.6 . 18.6/4=4.65 hope I helped

Answer: 26 pieces of $1 bill and 34 pieces of $5 bill
Total Deposit = $196 Total Bills = 60 pieces Value of $1 = $1 Value of $5 = $5
Lets assume all the 60 pieces were $1 bill. The total deposit will be 60 x $1 = $60
But we know that the total deposit is $196. So the extra value must have come from the $5.
$196 - $60 = $136 There is still an outstanding amount of $136 not accounted for.
$5 - $1 = $4 The difference in the two bills is $4
Now we can find out the number of $5 bill by dividing the extra $136 by 4: 136 ÷ 4 = 34 pieces
There are 34 pieces of $5 bill.
Since there are 34 pieces of $5, the rest must be the $1 bill 60 - 34 = 26
There are 26 pieces of $1 bill.
