Answer: Assets increase $13,800 and equity increases $13,800.
Explanation:
The Accounting equation is given as;
Assets = Equity + Liabilities
If a stockholder therefore gives $13,800 to the business, this will increase Equity by the same amount as the stockholder is an owner.
This increase in Equity as the equation shows, will have to translate to an increase in Assets by the same amount that Equity increased by which is $13,800.
