Answer:
Joey can avoid paying sales tax by purchasing the computer with his credit card, unlike Chandler.
Step-by-step explanation:
By using credit card, Joey will avoid paying sales-related taxes, or will have the reduced tax rate. This is because the credit card provides a form of payment, which in addition to allowing a purchase to be made quickly, managed to make the customer escape some, if not all, of the fees on products sold. On the other hand, Chandler has no credit card and is raising money to buy a computer. The problem with Chandler's payment method is that there is no device that frees you from paying taxes on the purchased product.
