Answer:
1560.38
Explanation:
As far as I know, a sales tax is never calculated until money changes hands. So the rebate is the first amount to take place.
1560 - 100 = 1460
Now if the purchaser agrees to this amount and does anything to pay partially or in full, the tax is added.
Total Cost = 1460 * (1.06875)
Total Cost = 1560.38
Edit
You have to be very careful when you use a term like rebate. Rebate is a very special kind of discount. Your purchase has to qualify for a rebate. Apparently this one does. If you are willing to spend 1560 on something, the merchant selling the product offers you a rebate to help you decide.
If the TV cost is 1200 you may not get the rebate.
