Answer:
a.increase in assets (Cash) and increase in owner's equity (Michael Anderson, Capital)
Explanation:
we solve this using the accounting equation
Assets = Liabilities + Equity
The cash would represent currency own by the company. That is the definition of assets. Something own by the company that either is cash or can be converted into cash in the future or help to provide an inflow of cash.
Now, as Asset increase by 15,000 the other side must also increase.
The company has no liability against the owner Thus this will be an equity account Which precisely, it represent the capital of the owners.
