Final answer:
Gina's gross income is $17,100.
Step-by-step explanation:
Gina's gross income can be calculated by adding up all of her income sources. Her income includes dividends of $2,100, earnings from babysitting of $1,000, nontaxable Social Security benefits of $10,000, and nontaxable interest from city bonds in the amount of $4,000. To find her gross income, we add all of these amounts together:
Gross Income = Dividends + Babysitting Earnings + Social Security Benefits + Municipal Bond Interest
Gross Income = $2,100 + $1,000 + $10,000 + $4,000
Gross Income = $17,100
