Arrange the following steps to demonstrate how an increase in investment spending leads to a change in real GDP through the multiplier effect:

When businesses increase their investment spending, they buy more equipment, buildings, or technology. This spending creates jobs and income for workers who build or create these goods, leading to more people having money to spend. As these workers spend their earnings on goods and services, businesses see higher sales and may invest even more to meet the increased demand. For example, if a company invests in new machinery, it might hire more workers, who then spend their wages at local shops. This cycle continues, and the overall economy grows, which is known as the multiplier effect, ultimately leading to an increase in real GDP.
