To calculate the number of orders of a breakfast sandwich and a cup of orange juice expect to sell, we need to find the proportion of orders that include that combination in the table.
The total number of orders in the table is 13 + 27 + 23 + 16 = 79.
The proportion of orders that include a breakfast sandwich and orange juice is 13/79 = 0.1646.
To predict the number of orders of a breakfast sandwich and orange juice if he had 1,765 customers, we multiply the proportion by the total number of customers:
0.1646 x 1,765 = 291
Therefore, Mitch would expect to sell 291 orders of a breakfast sandwich and a cup of orange juice.
So the answer is 291 orders.
