To calculate the gross income, we need to add up all the sources of income:
- Salary: $4,000 per month
- Side Job: $20 per hour for 10 hours a week for 4 weeks:
- Weekly income from side job: $20 * 10 hours = $200
- Monthly income from side job: $200 * 4 weeks = $800
- Rent from Roommate: $1,000 per month
Now we can sum these amounts:
- Salary: $4,000
- Side Job: $800
- Rent: $1,000
Total Gross Income = $4,000 + $800 + $1,000 = $5,800
Therefore, the correct option is $5,800.
