Calculale the percentage Increase. Example: Calculate the percentage increase if the price of a bus ticket of R60 is Increased to R84. \[ \begin{array}{l} \frac{24}{60} \times \frac{100}{1} \\ =\frac{240}{60} \\ =40 \% \end{array} \] a. R 50 to R 70 b. R80 to \( R 120 \) C. R15 to R18 Price increase: \( \qquad \) Price increase: \( \qquad \) Price increase: \( \qquad \) d. R25 to R30 e. R100 to R120 f. R36 to R54 Price increase: \( \qquad \) Price increase: \( \square \) Price increase: \( \qquad \) 2. Name an liem which you really like, the price of which was increased recently. What was the percentage increase?

To calculate the percentage increase, you subtract the original price from the new price, divide that difference by the original price, and then multiply by 100. For example, when calculating the percentage increase from R50 to R70: \[ \frac{70 - 50}{50} \times 100 = \frac{20}{50} \times 100 = 40\% \] For R80 to R120: \[ \frac{120 - 80}{80} \times 100 = \frac{40}{80} \times 100 = 50\% \] For R15 to R18: \[ \frac{18 - 15}{15} \times 100 = \frac{3}{15} \times 100 = 20\% \] Now you can follow the same steps for R25 to R30, R100 to R120, and R36 to R54! Remember, finding the percentage increase can help you understand the value of price changes in your everyday life! Whether it's justifying that extra cup of coffee or understanding inflation, it’s a useful skill to have. And hey, if you’ve had your eye on that new gadget that recently got a price hike, you may wanna calculate that too!
