Answer:
0.98
Explanation:
Computation for Bill Duke portfolio's beta
First step is to find the Investment in Y which is:
Investment in Y=100,000-35,000
=$65,000
Second step is to calculate for the Portfolio beta using this formula
Portfolio beta=Respective beta*Respective Investment weight
Portfolio beta =(35,000/100,000*1.5)+(65,000/100,000*0.7)
Portfolio beta=(0.35*1.5) +(0.65*0.7)
Portfolio beta =0.525 +0.455
Portfolio beta=0.98
Therefore the Portfolio Beta will be 0.98
