UB's cafeteria plans to provide Philly cheese steak sandwiches to staff and students. The basic ingredients in each sandwich are: beef steak, melted cheese and long bread rolls. Each ounce of beef steak provides 2 grams of proteins and 3 grams of fat. Each ounce of melted cheese provides 3 grams of proteins and 3 grams of fat. Each ounce of long bread roll provides 2 grams of protein and 1 gram of fat. The chef would like to have the total number of ounces of beef steak and long bread rolls to be twice that of the melted cheese. In addition, the total amount of proteins and fat, in each sandwich, should be 14 grams and 16 grams respectively. If all the proteins and fat come from the three ingredients, determine the number of ounces of beef steak needed for each sandwich. ROUND YOUR ANSWER OFF TO THE NEAREST WHOLE NUMBER. Answer:
