Grace packed 5 pairs of shoes, 3 pairs of pants, 8 shirts, and 3 jackets for her business trip. If an outfit consists of one of each item of clothing except shirts, of which she will wear 2, how many different outfits D can does Grace have available during her trip?  Choose the correct choice from the following:
A) 2,520  B) 1,260  C) 620  D) 360  E) 120
The idea is to multiply the number of possibilities for each item of clothing with the different items. For the shirts you essentially choose 2 out of 8 so you should use the combination forumla (don't know how to use math symbols here).   This gives you D=5 x 3 x 28 x 3 = 1'260. Hence, solution 1,260 is correct.
