Answer:
kim bought 12 sandwiches
Explanation:
total order = $35
potato salad costs = $5
remaining she spent on turkey sandwiches
amount spent on turkey sandwiches = 35 - 5 = $30
let x be the total number of sandwiches she bought
1 sandwich costs = $2.50
x sandwiches cost = $30
x = 30/2.50 = 12 sandwiches
thus,
kim bought 12 sandwiches
