you need diffrent combonations. So you could have only egg salad on white bread another time you could have all off the coices on rye bread.

15 days.
There are 5 different types of sandwich and 3 different breads, therefor, 5 x 3 =15!

I think its 72 days.
They didn't restrict the meat to 1 meat per sandwich.
