5. A store is offering a 25% discount on all items. Also, employees get a 10% employee discount. If you are an employee, which discount would you want to be applied first to save the most money?
It doesn’t matter which discount is applied first, the result is the same. ✅

The order in which the discounts are applied does not affect the final price. Whether the 25% discount is applied first and then the 10% employee discount, or vice versa, the final discounted price will be the same. Therefore, it does not matter which discount is applied first.
