Mitch owns a coffee shop and keeps track of how many orders he fills and in what combination of items they are during the first hour his shop is open. Combinations include either a breakfast sandwich or muffin and either orange juice or milk.

Mitch needs to predict how many orders of a breakfast sandwich and a cup of orange juice he would expect to sell if he had 1,765 customers.

To calculate the expected number of orders of a breakfast sandwich and orange juice out of 1765 customers, we look at the proportion of orders that consist of a breakfast sandwich and orange juice, which is 13 out of 79 total orders.

13/79 = approximately 0.1646

So, the number of breakfast sandwich and orange juice orders would be:
0.1646 * 1765 = 291 orders

Therefore, the answer is 291 orders.
