Final answer:
To maximize expected profit, you need to determine the amount to invest in stocks A, B, and C while considering the given constraints.
Step-by-step explanation:
To invest in each stock to maximize expected profit, we need to determine the amount to invest in stocks A, B, and C while considering the given constraints.
Let's denote the amount invested in stock A as x, in stock B as y, and in stock C as z.
The constraints are as follows:
- At least $1,000 should be invested in each stock: x > $1,000, y > $1,000, z > $1,000
- No more than $7,000 should be invested in stock C: z < $7,000
- The amount invested in C should be less than 4 times the amount invested in A: z < 4x
- The amount invested in B should be less than twice the amount invested in A: y < 2x
To maximize expected profit, we need to maximize the sum of the expected returns from each stock:
Expected profit = 0.04x + 0.05y + 0.06z
By solving the constraints and optimizing the expected profit function, we can find the optimal values for x, y, and z.
