Final answer:
The number of pieces of Cheesy Garlic Bread in an order can be determined by dividing the total number of bread slices by 2, since each sandwich requires 2 slices of bread. In this case, there are 28 slices of bread, so the order would consist of 28 pieces of Cheesy Garlic Bread.
Step-by-step explanation:
The number of pieces of Cheesy Garlic Bread in an order can be determined based on the given information. If 1 sandwich requires 2 slices of bread and 1 slice of cheese, we can divide the total number of bread slices by 2 to determine the maximum number of sandwiches that can be made. In this case, there are 28 slices of bread, so 28 / 2 = 14 sandwiches can be made. Since each sandwich consists of 2 pieces of Cheesy Garlic Bread, the total number of pieces is 14 x 2 = 28.
