Answer

Explanation:

Step1: Calculate the price after 30% markdown

The original selling price is $776. A 30% markdown means the customer pays (1 - 0.30) of the original price. So the price after the 30% markdown is $776\times(1 - 0.30)=776\times0.70 = 543.20$.

Step2: Calculate the price for club - members

Club - members get an additional 10% off the price after the 30% markdown. So they pay (1 - 0.10) of the price after the 30% markdown. The price club - members pay is $543.20\times(1 - 0.10)=543.20\times0.90 = 488.88$.

Answer:

a. $543.20 b. $488.88
