A certain taxi company charges $3.10 for the first of a mile plus $0.40 for each additional of a mile. What would this company charge for a taxi ride that was 8 miles long?
lz,这题目题干里条件应该不完全，我google了一下，原题是 A certain taxi company charges $3.10 for the first 1/5 of a mile plus .40 for each addtional 1/5 of a mile. What would this company charge for a taxi ride that was 8 miles long? 所以,就很简单拉，答案是D 3.1+[(8-0.2)/0.2 *0.4]
