To determine the weighted dollar amount for the savings account in the given investment portfolio, here are the detailed steps:
1. Identify the amount invested in the savings account and its rate of return (ROR).
- Amount invested in the savings account: [tex]$8,400.
- Rate of return for the savings account: 3.6%.
2. Convert the rate of return from a percentage to a decimal by dividing it by 100.
- 3.6% = 3.6 / 100 = 0.036.
3. Calculate the weighted dollar amount by multiplying the amount invested by the rate of return.
- Weighted dollar amount = Amount invested * Rate of return.
- Weighted dollar amount = $[/tex]8,400 * 0.036.
4. Compute the result:
- Weighted dollar amount = [tex]$302.40.
Therefore, the weighted dollar amount of the savings account is $[/tex]302.40, which matches the option:
[tex]\(\$ 302.40\)[/tex].
