A Correct answer
Explanation

L1 = (66 + 72) / 2 = 138 / 2 = 69. Selling prices: A=280, B=575, C=384, D=678, E=770. L2 = 280+575+384+678+770 = 2687. L1 + L2 = 69 + 2687 = 2756.

AI explanation

First, find L1 by averaging the discounts of articles C and D: (66 + 72) / 2 = 69. Next, calculate the selling prices for all articles by subtracting each discount from its marked price: A is 280, B is 575, C is 384, D is 678, and E is 770. Sum these selling prices to find L2: 280 + 575 + 384 + 678 + 770 = 2687. Finally, add L1 and L2 to get 69 + 2687 = 2756.
