The formula for calculating net income is accurately represented as net income equals gross income minus deductions. This formula captures the essence of net income by indicating that it is derived from the total income earned (gross income) after accounting for all the necessary deductions, such as taxes, retirement contributions, and other withholdings. By subtracting these deductions from gross income, you arrive at the amount of money that an individual truly retains as disposable income, which can then be used for spending, saving, or investing. This understanding highlights the importance of managing deductions effectively to maximize net income. The other options suggest incorrect operations, such as addition or multiplication, which do not accurately reflect the relationship between gross income and deductions.
