14.

A merchant offers a large group of items at 30%30\% off. Later, the merchant takes 20%20\% off these sale prices and claims that the final price of these items is 50%50\% off the original price. The total discount is

35%35\%

44%44\%

50%50\%

56%56\%

60%60\%

Answer: B
Concepts:percentage
Difficulty rating: 1180
Solution:

Let the original price be xx. After the 30%30\% discount, the price is 0.70x0.70x.

Taking another 20%20\% off that sale price leaves 0.800.70x=0.56x0.80\cdot0.70x=0.56x.

The customer pays 56%56\% of the original price, so the total discount is 44%44\%.

Thus, B is the correct answer.
