What is the annual income calculated from a monthly income of $3,500?

To determine the annual income from a monthly income of $3,500, you multiply the monthly income by the number of months in a year.

The calculation is straightforward:

$3,500 (monthly income) multiplied by 12 (months in a year) equals $42,000.

This method provides a clear understanding that to convert a monthly figure into an annual one, you simply scale it according to the time period involved—in this case, increasing from one month to twelve months. The annual income represents the total anticipated income over a year, hence providing a complete financial picture based on the consistent monthly earning. This makes $42,000 the correct choice for annual income.
