Answer

1. Calculate the following percentages: a. \(30\%\) of \(81.80\) is \(24.54\). b. \(80\%\) of \(R\,1.60\) is \(R\,1.28\). c. \(90\%\) of \(R\,0.10\) is \(R\,0.09\). d. \(20\%\) of \(R\,460\) is \(R\,92\). e. \(60\%\) of \(R\,5.40\) is \(R\,3.24\). f. \(20\%\) of \(86.40\) is \(R\,17.28\). 2. A pair of shoes originally costs \(R\,150\) with a \(25\%\) discount. After the discount, the final price is \(R\,112.50\).

When calculating discounts, it’s crucial first to understand the percentage off. In your shoe example, you received a R 258 discount on shoes that originally cost R 150. But wait! If the discount exceeds the price, that could be a key typing error. Double-check your figures and remember that a discount can’t be greater than the total price! For your question about finding percentages, it’s helpful to convert percentages into decimals to simplify calculations. For instance, 30% becomes 0.30 in computations. Multiply the total price by this decimal to find out how much you’ll pay. Practice these small methods to avoid common pitfalls, and you'll master this in no time!
