Final answer:
An upcharge in a food service setting is the additional cost for adding something extra to an order, similar to the extra $1 charged for both creamer and sweetener on top of the base $2 coffee price.
Step-by-step explanation:
The question asked is related to the concept of upcharges in the context of a food service setting, specifically regarding the additional cost for adding a crock of soup to a combo. To understand upcharges, consider the example of a coffee shop changing its pricing structure.
Previously, a cup of coffee cost $3, but with the new pricing, coffee itself costs $2, while creamer and sweetener now cost $1 each. If a customer still pays the usual $3 for coffee, they can only choose between creamer or sweetener. If they want both, they face an extra charge of $1, which is similar to the upcharge for adding the crock of soup to the combo. In the given scenario, wanting both creamer and sweetener can be equated to wanting soup with the combo; therefore, a customer should expect to pay an additional amount on top of the base price.
