Customer buys something for $6.35 and he gives you $20.25
How do you give him the correct change?
Don't do it conventionally
$20.25-6.35
On a register it is the opposite. Start with 6.35-25=$6.10+(90)=$7+(3)=10+(10)=20
Answer $13.90
$20.25-6.35

Answer $13.90
EXPLANATION 2
A cashier is able to gather the change in their hands as they calculate because they start with 6.35. Just subtract the 25¢cents from 35 now you got $6.10.... Now the equation begins. Pull 90¢ from drawer and you are at 7$, pull $3 from drawer and you are at $10, lastly pull $10 from drawer and you are at $20(we subtracted ¢25 earlier).... Giving the total of 13.90 without having to stop and use paper or a calculator.
