Round each grade’s reading minutes to the nearest thousand:
• 18,050
• 30,451
• 55,870
• 80,689
• 67,270
Then estimate how many more minutes are needed to reach 500,000.
Answer: Rounded: 18,000; 30,000; 56,000; 81,000; 67,000.
Total rounded = 18,000 + 30,000 + 56,000 + 81,000 + 67,000 = 252,000.
Needed to reach 500,000 = 248,000 more.
