Answer:
Total economic investment = $15.6 million
Explanation:
Economic investment is defined as addition that contributes to a company's capital stock. Examples of capital stock are new equipment, a housing facility, or a new materials for production.
In this scenario the addition to capital stock is by 12 restaurant buildings and additional equipment
Economic investment by building = 12 buildings * 1 million = $12 million
Economic investment from equipment = 12 buildings * 300,000 = $3,600,000
Total economic investment = 12 million + 3,600,000 = $15.6 million
