Step-by-step explanation:
The student is asked to calculate the weighted dollar amount of Stock C in an investment portfolio. To find this, you multiply the amount invested in Stock C by its rate of return (ROR). In this case, Stock C has an amount of $580 invested at a ROR of 12.9%.
You calculate the weighted dollar amount as follows:

- Multiply the amount invested by the decimal ROR: $580 × 0.129
- Calculate the result: $74.82
Therefore, the weighted dollar amount of Stock C is $74.82.
