Explanation:
We need to disclose how the impact in the accounting equation and the journal entry should be done:
Aug 1st the common stock is an equity account that is increasing 
we receive cash that is an asset 
August 4th we are using our cash to pay in advance the rent.
this gives a right to use the rental space for 3-months thus, it is not an expense is a new asset. There is no change in the accounting equation only the composition of assets changed. 
August 16th we recognize earnings through revenues account this increases the equity of the company as well as assets.
August 27th in this case we pay the salaries which are an incurred cost, therefore, expense. This decreases equity. 
We also use cash making assets to decrease as well.
