Answer: See below
Step-by-step explanation:
The total number of ordered sandwiches is 160
The total number of Turkey Sandwiches is 80
The ratio of Turkey to Roast Beef is 5:3
So from this, 5 times of a value is 80
So 5x = 80
And x = 16
So the Roast beef sandwiches are 16×3=48
Therefore, the table is:
Sandwich type    Number
Turkey             80
Roast Beef          48
Vegetarian          32
