Cost of the computer before tax = $1500 Percentage of sales tax taken = 7% Then The amount of sales tax taken = (7/100) * 1500 = 7 * 15 = 105 dollars So the total amount of sales tax taken is $105 Then The total cost of the computer after adding sales tax = (1500 + 105) dollars = 1605 dollars So $1605 is the total cost of the computer after adding 7% tax. I hope the procedure is clear enough for you to understand.
