A 20-problem Thanksgiving shopping simulation covering unit price, discounts, tax, markup, and percent change with answers.
Sale signs can hide the comparison that matters. Students calculate per-unit cost, distinguish dollars off from percent off, combine discounts with tax, and explain why reversing a percent change does not restore the original price.
Encourage multipliers such as 0.80 for 20% off and 1.07 for 7% tax. They reduce multi-step confusion and prepare students for exponential reasoning.
Compare offers using unit prices and percent multipliers. Round money to the nearest cent only at the end.

| Apples | 3 lb for $5.70 | 5 lb for $9.25 |
| Juice | 64 oz for $4.48 | 96 oz for $6.24 |
