A taxi ride cost a customer a total of $13.48, which included 4% sales tax and a $1 surcharge after the tax. What was the subtotal before the surcharge and sales tax?

A.$0.48
B.$12.00
C.$12.96
D.$312.00

答案和解析

答案：B

解析：

Option B is correct. The total minus the surcharge is 13.48-1, or 12.48 dollars. The subtotal before tax and surcharge is then 12.48 divided by the decimal equivalent of the sales tax percentage, 0.04, plus 1, or 12.48/1.04.
