14. Chef is making a new ?style? of salad, which will contain two kinds of lettuce, one kind of tomato, one kind of pepper and two kinds of squash. If Chef has 8 kinds of lettuce, 4 kinds of tomatoes, 5 types of peppers, and 4 kinds of squash from which to choose, than how many different ?styles? of salad can he make?
(A) 640
(B) 1120
(C) 2240
(D) 3360
(E) 13440

My working as follows
8ways to choose 1 kind of lettuce*7 second lettuce*4 kinds of tomatoe*5kind of pepper*4to choose 1kind of squash*3 to choose 2kind of squash
So 8*7*4*5*4*3=56*20*12=13440
