Answer:
To have one significant figure means to have one number with a significant value. Since all of the answers are greater than one, the final answer with the correct sig figs involves using the two leftmost numbers. If the second leftmost number is greater than 5, round the leftmost number up one unit. If the number is less than 5, leave the leftmost number alone. Finally, change all of the values besides the leftmost to zero. There should be no decimal place because having it would mean the zeros to the left of the decimal place are significant.

Answer: She bought about 150 markers.
Step-by-step explanation:
Given : A teacher bought 15 boxes of markers.
i.e. Total boxes of markers = 15
Each box contained 8 markers.
That is , the estimated number of markers in each box = 10 [∵ 8≈10 [Round to the nearest tens]]
Now , the total number of markers in all 15 boxes of markers = (15) x (10)
= 150
Hence, she bought about 150 markers.
