Answer 1

To find out how many toothbrushes the dentist ordered, you can multiply the number of boxes by the number of toothbrushes per box.

The dentist ordered 10 boxes and there are 15 toothbrushes in each box:

\[ 10 \text{ boxes} \times 15 \text{ toothbrushes/box} = 150 \text{ toothbrushes} \]

So, the dentist ordered 150 toothbrushes.

The correct response is: 150 toothbrushes.
