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

Two of the costs are fixed:
$1.07 for operating-system overhead
$4.35 for the mounting of a data tape
So, let's focus on $0.023 per millisecond of computer time.
Rewrite as: $0.023 for every 0.001 of a second
Multiply both numbers by 1000 to get: $23.00 for every 1 second
Multiply both numbers by 1.5 to get: $34.50 for 1.5 seconds
So, the computer time costs $34.50
$34.50 + $4.35 + $1.07 = MORE THAN $35.57
Answer: E
