Answer:
e. 1.23
Step-by-step explanation:
As we know that
Old investment = $90,000
And, the new investment = 1,000 shares × $10 = $10,000
So, the total investment = $90,000 + $10,000 = $100,000
Now the beta would equal to
= (New investment ÷ total investment) × new beta + old investment ÷ total investment) × new beta
= ($10,000 ÷ $100,000) × 1.50 + ($90,000 ÷ $100,000) × 1.20
= 0.15 + 1.08
= 1.23
