Discount Worksheet/Game Quiz/Worksheet
Welcome to Discount Worksheet/Game. This game is a simulation designed to help you master mental math for everyday transactions.

Scroll down the page for a more detailed explanation.
How to play the Discount Worksheet/Game
The Core Logic
The game uses two different math paths depending on the “Tag Type” shown in the top right corner of the price card.
SALE (Discount): You are lowering the price. Subtract the percentage from the original.
P - (P × %) = New Price
MARKUP: You are increasing the price (usually to cover costs or inflation). Add the percentage to the original.
P + (P × %) = New Price
How to Play
Identify the Action: Look at the color and text of the tag.
Red Tag (“SALE”): Subtract.
Yellow Tag (“MARKUP”): Add.
Calculate the “Adjustment”: Find the dollar amount of the percentage.
Example: Original is 80 and the adjustment is 25%.80 × 0.25 = 20.
Apply to the Original:
If it’s a Sale: 80 - 20 = 60.
If it’s a Markup: 80 + 20 = 100.
Submit: Type your final price and hit “Update Price Tag” (or press Enter).
Mental Shortcuts
You can use these mental math tricks instead of long multiplication:
| Adjustment | Mental Shortcut |
|---|---|
| 50% | Cut the price in half. |
| 25% | Divide by 4 (half of a half). |
| 10% | Move the decimal point one spot to the left. |
| 20% | Find 10% and double it. |
| 75% | Find 25% and multiply by 3. |
Complement Method
The formula is
Sale Price = Original Price × Complement Percentage
| Discount Rate | The Complement (What you pay) | Mental Fraction |
|---|---|---|
| 10% OFF | 90% | 9/10 |
| 20% OFF | 80% | 4/5 |
| 25% OFF | 75% | 3/4 |
| 50% OFF | 50% | 1/2 |
| 75% OFF | 25% | 1/4 |
