(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.

(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.

I suppose it can help to save time and time is a very, maybe even the most valuable resource.

Because, the total discount is not 20% but slightly less than 20%.
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.
