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?

C.$12.96
D.$312.00
重点单词
equivalent [i'kwivələnt] adj. 等价的，相等的
surcharge ['sə:.tʃɑ:dʒ] n. 装载过多，额外费
option ['ɔpʃən] n. 选择权，可选物，优先购买权
multiple ['mʌltipl] adj. 许多，多种多样的
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.
