Answer:
20
Explanation:
To know how many students will be in the country spelling bee, we need to find 5% of 400.
So, we need to multiply 400 by 5 and then divide by 100:
[tex]400\times5\text{ \%=}\frac{400\times5}{100}=\frac{2000}{100}=20[/tex]Therefore, there will be 20 students in the country spelling bee.
