Can you help me with this assignment? Thanks in advance

Suppose you have $$10,000$ to spend on building a computer system intended to service $10$ users.

The system consists of $10$ terminals $($one per user$),$ a single CPU, and a set of identical disk drives.

The CPU comes in $3$ models: A$,$ B$,$ and C$.$ Each user job requires an average of $40$ ms of service

time per visit to the model A CPU, $20$ ms of service time per visit to the model B CPU, and $12$ ms

of service time on the model C CPU. Each user job requires an average of $40$ ms of service time per

visit to a disk. The disk load is balanced regardless of the number of disks. That is$,$ if the system

has a single disk drive, $100\%$ of the user requests go to that disk; if the system has $10$ disks, each

disk gets $10\%$ of user requests, etc. User think times are $10$ seconds on average. A user job leaving

the CPU returns to its terminal with a probability of $0\mathrm{.}01.$ Jobs leaving a disk always go back to

the CPU. Model A CPU costs $$4,000,$ Model B costs $$6,000$ and Model C costs $$7,000.$ Each disk

drive costs $$1,000.$

What is the optimistic steady$-$state system throughput at $10$ users for each CPU model and as

many disks as the CPU price and the total budget of $$10,000$ allows?
