Rounding dollar amounts to the nearest 10 cents (A) - Free Printable

Problem Description:

The task is to round each given dollar amount to the nearest 10 cents. The instruction specifies that the "≈" sign means "approximately equal to." This involves rounding the cents portion of each dollar amount to the nearest multiple of 10 cents.

Solution Approach:

To round a dollar amount to the nearest 10 cents:
1. Identify the cents portion: Focus on the digits after the decimal point.
2. Determine the nearest 10 cents:
- If the cents are 0–4, round down to the nearest 10 cents.
- If the cents are 5–9, round up to the nearest 10 cents.
3. Adjust the dollars if necessary: If rounding causes the cents to cross over a whole dollar boundary, adjust the dollar amount accordingly.
