The traditional way starts from the cost and counts up to the amount 
tendered. So to make change from $10 for $5.77 you would count
three pennies -> $5.80
two dimes -> $6.00
four $1 -> $10

The modern way seems to be to look at the change amount given by the 
cash register and count that out starting with dollars...
