Art supplies in Washington, D.C. Cost 28. If the sales tax is 6%, what was the total cost of supplies?

Answers

If the art supplies cost $28 and the sales tax is 6%, you must find 6% of 28. To do this, you must multiply 6 by 28, and then divide by 100. The result is 1.68. Then, to find the final cost, add the 6% of 28 (which is 1.68) to the original cost, $26, which is $29.68
Sales tax is:
$28.00* (6/100)= $1.68

$28.00+ $1.68= $29.68

The total cost of supplies was $29.68.
