-
A
Assume it is fine and complete the sale
-
B
Pause to verify the entry before finalizing, correcting it if needed, so the customer is charged accurately
-
C
Charge a round number to keep it simple
-
D
Let the customer point out any mistake
Why this is the answer
Transaction accuracy protects both the customer and the Postal Service's records, and the exam values careful, accurate work. When unsure about an entry, the best action is to pause and verify it before finalizing the sale, correcting any error so the customer is charged accurately. Assuming it is fine, charging an arbitrary 'round' amount, or relying on the customer to catch mistakes all risk incorrect charges and accountability problems. The VEA rewards conscientious attention to detail in transactions, because accurate ringing-up is fundamental to trustworthy retail service and proper financial records.
