Assume that we are considering enhancing a quad-core machine by adding encryption hardware to it. When computing encryption operations, it is 25 times faster than the normal mode of execution. We will define percentage of encryption as the percentage of time in the original execution that is spent performing encryption operations.

With what percentage of encryption will adding encryption hardware result in a speedup of 2?

Please show all steps and equations
