Some people choose to put different types of food on their sandwiches that you wouldnt normally put on a hot sandwich.
For example if you were going to make a hot sandwich, it would have things like grilled chicken, fish, cooked and hot items.
most likely the orange juice is made out of a Navel Orange because they have a more sugary taste then the rest of the oranges that you named and have a stronger pigment
What i understand from the statement given is that the expression will be:
10m + n/4
where m = 5 and n = 16
now by putting the values of m and n in the expression,we get
10(5) + 16/4
=50 + 4
= 54
Thus, after solving the expression we get the answer 54.
