Answer:
Kim had bought 12 sandwiches.
Step-by-step explanation:
Given:
Amount spend at Midtown Dine = $35
Amount spend on large order of potato salad = $5
Cost of each sandwich = $2.5
We need to find the number of sandwich did Kim bought.

Subtracting both side by 5 we get;

Dividing both side by 2.5 we get;

Hence Kim had bought 12 sandwiches.
