The answer is $4.85;$81.85  which is B. 

Answer:

$4.85;$81.85

Step-by-step explanation:

The total cost of an item is the addition of the list price with the sales tax. The sales tax is a fraction of the list price.

Sales price = ?

List price = $77

Sales tax rate = 6.3%

Sales tax paid = 6.3% × $77 = $4.85

Total cost of the pair of earrings = $77 + $4.85 = $81.85
