Answer:
Project order from the smallest to the largest is as follows:
1. Software with $50,000
2. Hardware with $650,000
3. Biotech firm with $850,000
Explanation:
Weighted returns for each project
Software returns= $(5%*8,000,000+30%*1,000,000 +65%*-1,000,000) =$50,000
Hardware returns=$(15%*3000000+50%*1000000+35%*-1000000)
=$650,000
Biotech firm returns=$(20%*7,000,000+25%*0+55%*-1,000,000)
=$850,000
