Step 1 :Let's denote the price of Falafel wrap as F, the price of Turkey BLT as T, and the price of Hot Ham and Swiss as H.
Step 2 :From the problem, we can set up the following system of linear equations: \(5F + 15T + 20H = 260\), \(8F + 18T + 14H = 263\), and \(12F + 16T + 12H = 258\).
Step 3 :Solving this system of equations, we find that F = \(\frac{11}{2}\), H = 6, and T = \(\frac{15}{2}\).
Step 4 :Thus, the price of each sandwich is: Falafel Wrap = \(\boxed{\$5.50}\), Turkey BLT = \(\boxed{\$7.50}\), and Hot Ham and Swiss = \(\boxed{\$6.00}\).
