22. a shopping mall in the greater bay area is having a sale. a piece of clothing originally costs 200 yuan. it is first discounted by 20% (eight - fold), and then the price is reduced by another 20 yuan. what is the current price of the clothing?

Answer

Answer:

128 yuan

Explanation:

Step1: Calculate the price after the first discount

The original price is 200 yuan, and it is first discounted by 20%. The formula for calculating the price after the first discount is (P_1 = 200\times(1 - 20%)). [P_1=200\times0.8 = 160]

Step2: Calculate the current price

Then it is reduced by another 20% (eight - fold). The formula for calculating the current price (P) is (P=P_1\times(1 - 20%)). Substitute (P_1 = 160) into the formula: [P = 160\times0.8=128]
