Q. Isabella went shopping for a new phone because of a sale. The store was offering a 20% 20 \% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?\newlineAnswer:
  1. Calculate Percentage of Original Price: Isabella wants to find the price she would have to pay after a 2020\% discount is applied. To do this in one step, she needs to calculate the percentage of the original price that she will actually pay. If the discount is 2020\%, then she will pay 100%−20%100\% - 20\% of the original price.\newlineCalculation: 100%−20%=80%100\% - 20\% = 80\%
  2. Multiply Prices by 0.800.80: To find the price she would have to pay before tax, Isabella should multiply the prices on the tags by 0.800.80, which represents 80%80\% in decimal form.\newlineCalculation: 20%20\% discount means she pays 80%80\%, so the multiplier is 0.800.80.
