Workkeys Math Practice Test

To find the percentage increase, you start by calculating the difference between the new price and the original price. In this scenario, the price rises from $50 to $65, which gives a difference of $65 - $50 = $15. Next, to find the percentage increase relative to the original price, you take the difference ($15) and divide it by the original price ($50). This calculation is expressed as: \[ \frac{15}{50} = 0.30 \] To convert this decimal into a percentage, you multiply by 100: \[ 0.30 \times 100 = 30\% \] Thus, the percentage increase in the price of the item is 30%. This confirms that the calculated value aligns with the answer choice indicating that the percentage increase is 30%.
