Answer:
the total of quick assets is 173,000
Step-by-step explanation:
 
assets are fast, they are those that are considered current, that is, in less than a year they can be used to cancel liabilities or acquire other goods. 
First we dismiss all liability accounts. 
Then we analyze the possibility of assets "becoming" money in less than a year. 
They are the following items:
Accounts receivable 45,000
Cash 20,000
Inventory 72,000 
Marketable securities 36,000 
Total = 173,000
