Answer:
Correct option is A
Step-by-step explanation:
Invoiced purchases are $ 3,000, out of which $ 800 worth of goods were returned, and an extra shipping charge of $ 250 needs to be paid. 
 
Total amount of the invoice 3,000 
 
Add: Shipping Charges 250 
 
Less: Value of goods return (800) 
 
Amount to be paid $2,450 
 
There will be no discount to be deducted because the invoice was not paid within the 10 days discount period. 
 
$2,450
