In a city that has a 6 percent sales tax rate, Vinod purchases a cotton shirt and a cashmere sweater. If the cost of the shirt, excluding sales tax, is $100, what was the total amount that Vinod paid for the shirt and sweater, including sales tax?
(1) The sales tax on the sweater is $19.20.
(2) The total sales tax is $25.20

From S2, $25.20
