Theory:
Change Due
Change is the money a customer
receives back when they have made a purchase. Often the customer gives the
merchant more money than the amount due because the customer may not have the
exact coins and bills that are needed. The merchant determines how much extra
was paid and returns the excess that is called change.
How to Find the Least Number of Coins to give in Change:
Determine the total amount of change due.
Use as many of this coin as possible without exceeding the
amount of change due
Repeat this process with the next lowest denomination of
coin or bill
Example of making change for purchase of $2.11 and customer
paying with a $20.00 bill
Determine change due -- $20.00 - $2.11 = $17.89
Get one $10 bill but two would be too much -- have $10.00
for change
Get one $5 bill but two would be too much -- have $15.00
for change
Get two $1 bills but three would be too much -- have $17.00
for change
Get 3 quarters but four would be too much -- have $17.75
for change
Get 1 dime but two would be too much -- have $17.85 for
change
Get 0 nickels - even one would be too much -- have $17.85
for change
Get 4 pennies - 5 would be too many -- have $17.89 for
change
