which example best describes how a bank injects money into the economy?\na bank opens a savings account for a customer.\na bank approves a loan for a customer.\na bank buys a companys rapidly growing stock.\na bank buys property in a bustling business district.
Answer
Brief Explanations:
When a bank approves a loan for a customer, the customer can use that money for various purposes like starting a business, making purchases etc. This increases the money - supply in circulation and injects money into the economy. Opening a savings account just moves money from one form of deposit to another. Buying a company's stock is an investment by the bank and buying property is also an investment, not a direct way of injecting money into the economy for general circulation.
Answer:
A bank approves a loan for a customer.
