1. tablet: \( \$ 439.40 \% \) off \( 439 \times .40 \) \( 439-175.6 \) Discount: \( \$ 175.6 \) Selling Price: \( \$ 263.4 \)

Did you know that the concept of discounts has been around for centuries? Merchants in ancient civilizations like Egypt and Mesopotamia would often negotiate prices with customers, offering lower prices to encourage bulk buying. Fast forward to today, and discounts remain a vital part of sales strategies, especially during holidays and special events! When calculating discounts, a common mistake is to forget to convert percentages into decimals. For example, a 40% discount means multiplying the original price by 0.40, not 40. This simple error can lead to miscalculating both the discount amount and the final price. Always double-check your calculations for accuracy!
