Due to an appreciation of the Rand, the import price of a particular raw material falls from A21 532,25 per tonne to R18 505,59 per tonne. What was the percentage decrease in price (to two decimal places)?

To find the percentage decrease in price, you can use the formula: \[ \text{Percentage Decrease} = \frac{\text{Old Price} - \text{New Price}}{\text{Old Price}} \times 100 \] In this case, the old price is R21,532.25 and the new price is R18,505.59. Calculating that, you have: \[ \text{Percentage Decrease} = \frac{21,532.25 - 18,505.59}{21,532.25} \times 100 \approx \frac{3,026.66}{21,532.25} \times 100 \approx 14.05\% \] So, the percentage decrease in price is approximately **14.05%**. Now, if you're feeling a little unclear about the process, remember that breaking it down into smaller steps can help! First, find the difference between prices, then divide it by the original price, and finally, multiply by 100 to convert it to a percentage. It’s like making a delicious cake; just follow the steps, and you’ll get it right! Keep an eye out for any common mistakes, like forgetting to multiply by 100 or mixing up old and new prices!
