The table shows the orders of sandwiches from a deli.

To determine the new ratio of turkey sandwiches to veggie sandwiches after Mr. Hernandez turns in his late order, we first need to update the current counts.

Initially, prior to the late order:
- Turkey sandwiches: 2
- Veggie sandwiches: 4

After Mr. Hernandez's late order for 1 turkey sandwich:
- New count of turkey sandwiches: \( 2 + 1 = 3 \)
- Veggie sandwiches remain the same: 4

Now, we have:
- Turkey sandwiches: 3
- Veggie sandwiches: 4

Next, we can write the ratio of turkey sandwiches to veggie sandwiches:
\[
\text{Ratio} = \frac{\text{Turkey sandwiches}}{\text{Veggie sandwiches}} = \frac{3}{4}
\]

Thus, the new ratio of turkey sandwiches to veggie sandwiches is 3 turkey sandwiches to 4 veggie sandwiches.

The correct answer is: **3 turkey sandwiches to 4 veggie sandwiches.**
