need help with this... please show all steps and logic used to solve for the answer

Suppose you have the new Zarnex VQ-120 computer which has a 64-bit architecture. Further, the boss has told you to max out the memory, which, on that machine, means you can install all the memory the architecture supports: how many bytes is that? At contemporary memory pricing of $7 / GB, how much will it cost to fill the machine? Knowing what you know about virtual memory, how much will it cost to provide disk space only for paging assume you need 2 real memory size for paging space, as many systems recommend. Use a price of $35/TB for disk pricing. Remember to include correct units on all your results the result isnt completely correct without them.
