Final answer:
Rosemary's loan affects two parts of the accounting equation as her company's assets and liabilities both increase by $1500. Equity remains unchanged until loan payments are made.
Step-by-step explanation:
When Rosemary got a 24-month 0% loan from a store to buy a copier costing $1500, it impacted two parts of the accounting equation: Assets increase and Liabilities increase. The copier is added to the company's assets, raising the asset value by $1500. Simultaneously, taking out the loan increases the company's liabilities by the same amount since it represents money that must be repaid to the lender, even though it is at 0% interest.
Equity would remain unchanged because no additional investment was made by the owners, nor were there any profits or losses from the transaction directly. Equity would only increase as Rosemary makes payments on the loan, effectively transferring value from liabilities to equity.
