请教一道数学题

s

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

1毫秒是1秒的0.001.计算机的运行一次程序的花费包括操作系统的内部整理自检程序1.07美元，每毫秒0.023美元的运行时间加上装配数据带的费用4.35美元。如果运行一个1.5秒的程序，这3个花费的总和是多少？

所以是1.5/0.001*0.023+1.07+4.35=39.92
