Worked Solution

Step 1: Identify the rounding place — nearest thousand. The thousands digit in 48,750 is 8. Step 2: Look at the digit immediately to the right of the thousands place — the hundreds digit. The hundreds digit is 7. Step 3: Apply the rule: if the digit to the right is 5 or more, round the thousands digit up; if less than 5, keep it the same. Here 7 ≥ 5, so 8 rounds up to 9. Step 4: Replace the hundreds, tens and ones with zeros. Final: $48,750 rounded to the nearest thousand is $49,000. Answer: $49,000

Correct answer: $49,000
