Step-by-step explanation:
The cashier should c.Ask the customer to add more items to reach $100 and then give a 10% discount.
Since the customer's purchase total is $95, which is less than $100, they do not qualify for the 10% discount. The cashier should ask the customer to add more items to their cart in order to reach $100, at which point they will be eligible for the discount.
