Final answer:
The unit cost of each boxed lunch is found by dividing the total cost ($185) by the number of lunches (25), which comes out to $7.40 per lunch.
Step-by-step explanation:
To find the unit cost of each boxed lunch, the total cost of all the lunches ($185) needs to be divided by the number of lunches ordered (25).
Step 1: Calculate the unit cost by dividing the total cost by the number of units.
Unit cost = Total cost ÷ Number of units
Unit cost = $185 ÷ 25
Unit cost = $7.40
So, the unit cost of each boxed lunch is $7.40.
