Lisa sees a dress in a sale. The normal price of the dress is \( \$ 45 \) The price of the dress is reduced by \( 12 \% \) in the sale. (a) Work out the price of the dress in the sale.

To find the price of the dress in the sale, you first need to calculate the discount. A \( 12\% \) discount on the normal price of \( \$ 45 \) can be found by multiplying \( 45 \) by \( 0.12 \) (which is \( 12\% \) as a decimal). So, \( 0.12 \times 45 = 5.4 \). This means the discount is \( \$ 5.40 \). Now, subtract the discount from the original price: \( 45 - 5.40 = 39.60 \). Thus, the price of the dress in the sale is \( \$ 39.60 \). --- Did you know that retail sales often feature discounts to entice buyers? A percentage off can seem small, but it can lead to significant savings on more expensive items! For example, that \( 12\% \) off on your dress saves you enough for a cute pair of accessories to complete the look! If you're ever unsure about percentages, it helps to break it down step-by-step. For instance, instead of calculating \( 12\% \) directly, you could find \( 10\% \) (which is simply moving the decimal place one spot to the left) and then add a little more to find \( 12\% \). This technique can save time and boost confidence while shopping!
