(A) $92.00
(B) $88.00
(C) $87.04
(D) $80.96
(E) $80.00 Quite straightforward. 10*10*.88*.92 = 80.96 Doubt if this is a 600-700 level question. Kudos Please... If my post helped.

(A) $92.00
(B) $88.00
(C) $87.04
(D) $80.96
(E) $80.00 Without any discount Sam should pay 10*10=$100. Now, the overall discount would be slightly less than 20%, thus he must pay slightly more than $80. Only answer choice D fits. Answer: D.

Answer: D.
Bunuel, Where is it possible to learn more about such elimination techniques? I suppose it can help to save time and time is a very, maybe even the most valuable resource.

Notice, the discount is 8% on 12% discounted price to be precise: 19.04% (obtained from 1 - (0.88*0.92) ) What Bunuel mentioned is approximation technique, slightly less than 20, so answer must be slightly above 80. Hope it helps.
