A) 84%
B) 85%
C) 15%
D) 16%

Answer 1

By subtracting the number of students who ride the bus from the total and then calculating the percentage, it is found that 16% of Mrs. Barrera's students do not ride the school bus every morning, which is option D.

Step-by-step explanation:

To find out what percent of Mrs. Barrera's students do not ride the school bus every morning, we should first determine how many students do not ride the bus. This can be done by subtracting the number of students who ride the bus from the total number of students. Mrs. Barrera has 25 students in total and 21 of them ride the bus. So the number of students who don't ride the bus is 25 - 21, which is 4 students.

Next, to find the percentage, we'll use the following formula:

(Number of students who don't ride the bus / Total number of students) × 100%.

That gives us (4 / 25) × 100% = 16%.

Therefore, the correct answer is D) 16%, which is the percent of Mrs. Barrera's students who do not ride the school bus every morning.
