Answer:
a. $28 million
b. $15 million.
Explanation:
a. The amount of economic investment that has resulted from BBQ's actions can be calculated by summing up the cost of building 20 new restaurants and the cost of outfitting them with equipment and furnishings.
![\textsf{Each restaurant costs \$1 million, and the additional equipment and furnishings cost \$400,000 per restaurant. }]()
So:
![\begin{aligned}\textsf{ Total economic investment }&\sf = (20 restaurants * 1,000,000 \textsf{per restaurant)} + (20 restaurants * 400,000\textsf{per restaurant) }\\\\ &\sf = 20,000,000 + 8,000,000 \\\\ &\sf = 28,000,000 \end{aligned}]()
Therefore, the amount of economic investment is $28 million.
