A teacher bought 15 boxes of markers. Each box contained 8 markers. Estimate how many markers she bought by rounding the number of markers in a box to the nearest ten.

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.
