Depends, are the goods faulty?
The price of with tax is 105% of the original price. That means the total is:
total = $4.80 * 105% = $4.80 * 1.05 = $5.04
So the customer should receive $5.04 for returning the item.
That would be 4.80 plus 5 percent of 4.80.
So it would be 4.8 times 1.05.
(Doesn't the cash register calculate this automatically?)
5.04
The price on item is 4.80 an the tax is 5%how much including tax should the cashier refund to customer?
