Answer:
Option B,only Phoenix option is correct
Explanation:
Firstly,we need to determine the current ROI of the Red,White and Brew Restaurants as shown thus:
ROI=controllable margin/invested capital
controllable margin is $250,000
invested capital is $2,000,000
ROI=$250,000/$2,000,0000=12.5%
Judging from a 12.5% ROI,any project whose ROI is higher than the current one would increase Red,White and Brew division's ROI
In essence Phoenix project would be the appropriate project as it has a higher ROI while Chicago project would be rejected based on a lower ROI.
