Explanation:

Step1: Analyze rounding for question 1

The number 806 has 6 in the ones - place. Since 6 > 5, when rounding to the nearest ten, we add 1 to the tens - digit. So 806 rounds to 810.

Step2: Calculate pages read for question 2

Harvey reads 17 pages per hour and reads for 6 hours. We use multiplication: \(17\times6 = 102\) pages.

Step3: Calculate earnings for question 3

Tyler mows 7 lawns per week and earns $10 per lawn. In one week, he earns \(7\times10=70\) dollars. In 6 weeks, he earns \(70\times6 = 420\) dollars.

Step4: Analyze number representation for question 4

22,211 is written as "Twenty - two thousand, two hundred eleven" and in expanded form is \(20000 + 2000+200 + 10+1\).

Step5: Calculate nail box difference for question 5

The store has 1056 boxes of long nails and 502 boxes of short nails. The difference is \(1056−502 = 554\) boxes.

Step6: Calculate craft - stick usage for question 6

Wendell has 213 craft sticks and 99 left. He used \(213−99 = 114\) craft sticks.

Step7: Calculate work hours for question 7

Charles works 40 hours per week for 50 weeks. We multiply \(40\times50\). Using basic facts, \(4\times5 = 20\), and then adding two zeros (because of the place - value of 40 and 50), we get 2000 hours.

Step8: Compare numbers for question 8

37,770 has a ten - thousands digit of 3 and a thousands digit of 7, while 30,707 has a ten - thousands digit of 3 and a thousands digit of 0. So \(37770>30707\).

Answer:

1. C. 810 marigold seeds
2. A. 102 pages
3. D. $420
4. Twenty - two thousand, two hundred eleven; \(20000 + 2000+200 + 10 + 1\)
5. 554 boxes
6. 114 craft sticks
7. 2000 hours
8. 37,770 is greater.
