Final answer:

The total number of electric toothbrushes shipped is the sum of defective and non-defective ones, which equals 20. There were 3 defective and 17 non-defective toothbrushes sent to the drugstore.

Step-by-step explanation:

A student asked how many electric toothbrushes were shipped in total if three defective electric toothbrushes were accidentally sent to a drugstore by CleanBrush Products along with 17 non-defective ones. To calculate the total number of electric toothbrushes, we simply add the number of defective toothbrushes to the number of non-defective toothbrushes.

Let's do the math:

Therefore, the correct answer to how many electric toothbrushes were shipped in total is 20.
