Computer Execution Time Problem

Homework Statement

Homework Equations

• CPU Time= Σ(individual IC time)

The Attempt at a Solution

What I did was first find the integer time, which is 100=75+X, and X is 25. To find the percent reduced,
I did 100(1-x)=75+25(1-0.5). This means x is 0.125 or 12.5 %.

Is this correct?

Yes

I agree with @phinds. But beware the trap, percentage of what?

It is like the sales tax problem. An item sells for $1. The tax is $0.10. so the total is $1.10. Is the tax 10/100=10% or 10/110=9.08%. Different states and different countries require one of those definitions by law and forbid the other definition.
