customers

Explanation:

Step1: Identify the percentage for roast beef

The percentage of customers who picked roast beef sandwiches is 35%, which can be written as 0.35 in decimal form.

Step2: Calculate the number of customers

To find the number of customers who picked roast beef, we multiply the total number of customers (320) by the percentage of roast beef customers (0.35). So the calculation is $320\times0.35$.
Calculating $320\times0.35$: $320\times0.3 = 96$ and $320\times0.05 = 16$, then $96 + 16 = 112$.

Answer:

112
