Calculate the weighted execution time of the FIRST TWO benchmarks.

Imagine that your company is trying to decide between a single-processor system and a dual-processor system. Figure below gives the performance on two sets of benchmarks- a memory benchmark and a processor benchmark. You know that your application will spend 60% of its time on memory-centric computations, and 40% of its time on processor-centric computations.
