Answer:
To 3 decimal places, the cost of the television is $662.377
Explanation:
Price = $621.95,
Sales tax = 6.5% of the price so,
Sales tax = (0.065)(621.95)
Sales tax = $40.42675
Hence including the tax, we have,
Total cost = Price + sales tax
Total cost = 621.95 + 40.42675
Total cost = $662.37675
Or, to 3 decimal places, $662.377
