Table 11.2 shows an execution mix and runtimes for two computers, System A and System C. In this example, System C is 83% faster than System A. Table 11.3 shows runtimes for System A with a different execution mix. Using the execution mix in Table 11.3, calculate the percentage by which System C would be faster than System A. Using the original statistics from Table 11.2, by how much has the performance of System A degraded under the new execution mix?
