Cannot be determined, because tax and deductions are not provided

To calculate the individual's gross income, we need to add together their salary, earnings from the side job, and the rent they receive.

Salary = $4000 per month
Side job = $20 per hour x 10 hours per week x 4 weeks = $800 per month
Rent = $1000 per month

Gross income = Salary + Side job + Rent
Gross income = $4000 + $800 + $1000
Gross income = $5800

Therefore, their gross income is $5800.
