While shopping in Georgetown, Ruben bought a wooden bench that was marked down 80% from an original price of $66.72. If the sales tax in Georgetown is 5%, what was the total cost of the wooden bench?

$66.72 * 0.20 ==$13.34 - cost of the wooden bench before sales tax

$13.34 * 1.05 ==$14.01 - cost of the wooden bench after 5% sales tax.
