Answer: 13.5%
Step-by-step explanation:
From the question, we are informed that an individual invest $15,000 in Merck stock and $25,000 in Home Depot stock and expect a return of 16% for Merck and 12% for Home Depot.
The expected return on the portfolio will be:
= [($15,000/$40,000) × 16%] + [($25,000/$40,000) × 12%]
= (0.375 × 0.16) + (0.625 × 0.12)
= 0.06 + 0.075
= 0.135
= 13.5%
