Answer: 30 percent of people who do not brush theit teeth every night.

Step-by-step explanation:

Given : 7 out of 10 people brush their teeth every night.

That means 3 out of 10 people do not brush their teeth every night. (7-10=3)

Now, the percent of people who do not brush their teeth every night = \dfrac{\text{Number of people do not brush their teeth}}{\text{Total people}}\times100\%

=\dfrac{3}{10}\times100\%\\\\=30\%

Hence, 30 percent of people who do not brush theit teeth every night.
