Final answer:
The cashier should calculate a 10% discount on the $95 purchase, which results in a discount of $9.50, making the total amount payable by the customer $85.50.
Step-by-step explanation:
The student's question is related to applying a discount to a purchase. In this case, if customers spend $100, they receive a 10% discount. The question describes a scenario where the cashier rings up a total of $95. Assuming the discount has not yet been applied, and there is no indication that the amount needs to meet or exceed $100 before a discount is given, the cashier should calculate 10% of $95 to determine the discount amount. Then the cashier should subtract this discount from the $95 to find the final amount the customer should pay.
To find the discount, convert 10% to a decimal (0.10) and multiply by $95:
$95.00 x 0.10 = $9.50
Subtract the discount from the total cost:
$95.00 - $9.50 = $85.50
Therefore, the customer should pay $85.50 after the discount has been applied.
