Answer:
A.
Step-by-step explanation:
The 8 in samira's is in the thousands place, that is, it represents 8000.
The 8 in Tineka's number is in the hundreds place, that is, it represents 800.
Now, clearly the 8 in Samira's number is bigger than the 8 in Tineka's number, also we have that
8000 = 800*10. Then, 8000 is 10 times 800. Therefore, the 8 in Samira's number is 10 times greater than the value of the 8 in Tineka's number.
So, the answer is A.
