🔍 What is the Dollar-Up Method?
The
Dollar-Up Method is a money estimation strategy used to make change easier when paying with cash. Here's how it works:
1.
Round up the price of an item to the next whole dollar.
2.
Give that amount to the cashier.
3. The cashier gives you back the difference (the change).
For example:
- If something costs $6.19, round up to $7.00.
- You give $7.00.
- The cashier gives you back $0.81 in change.
We’ll use this method for each item.
