Consider a memory system with cache having the following parameters:

Sc = 32 KB Cc = 0.1 cents/bytes T_C = 10 ns

Sm = 256 MB Cm = 0.0001 cents/bytes T_m = 100 ns

a. What was the total cost prior to addition of cache?
b. What is the total cost after addition of cache?
c. What is the percentage decrease in time due to inclusion of cache with respect to a system without cache memory considering a cache hit ratio of 0.85?
