Answer:
Project B
Step-by-step explanation:
The return on investment(ROI)=annual earnings on investment/initial investment
For project A,return on investment=$90,000/$800,000=11.25%
For project B,return on investment=$20,000/$100,000=20.00%
For project C,return on investment=$25,000/$300,000=8.33%
For project D,return on investment=$60,000/$400,000=15.00%
Since the investment manager is only interested in project that has at least 16% return on investment,the only project worthy of investing in is project B with return on investment of 20%
