Q. Isabella went shopping for a new phone because of a sale. The store was offering a 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?Answer:
Calculate Percentage of Original Price: Isabella wants to find the price she would have to pay after a 20\% 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 20\%, then she will pay 100%−20% of the original price.Calculation: 100%−20%=80%
Multiply Prices by 0.80: To find the price she would have to pay before tax, Isabella should multiply the prices on the tags by 0.80, which represents 80% in decimal form.Calculation: 20% discount means she pays 80%, so the multiplier is 0.80.
