各位xdjm,我完全被以下这道题的描述绕晕了,请帮帮忙翻译一下,谢谢。
One millisecond is 0.001 of a second. The costs for a single run of a computer program are $1.07 for operating-system overhead, $0.023 per millisecond of computer time, and $4.35 for the mounting of a data tape. What is the total of these three costs for 1 run of a program that requires 1.5 seconds of computer time?
(A) $7.15 (B) $8.87 (C) $28.96 (D) $35.57 (E) $39.92
答案给的是E |
