If a new phone costs $250 and a used one costs $75, what would be the total income from selling one new and one used?

To determine the total income from selling one new phone and one used phone, you simply need to add the prices of both phones together. The new phone costs $250, and the used one costs $75.

When you add these amounts—$250 + $75—you get a total of $325. This calculation shows that the total income from selling both phones is $325.

Understanding this basic arithmetic operation is crucial for handling similar financial questions, whether related to retail pricing, budgeting, or financial projections in various scenarios.
