A company orders 16 boxed lunches from a deli for $138.40. If each boxed lunch costs the same amount, what is the unit cost of each boxed lunch?

To find the unit cost of each boxed lunch, divide the total cost by the number of boxed lunches: $138.40 / 16 lunches = $<<138.40/16=8.65>>8.65 per lunch. Answer: \boxed{8.65}.
