djyliett [7]

Answer:

Total number of students receiving A grade = 75

Step-by-step explanation:

Total number of students enrolled in elementary algebra this year =300

Percentage of students receiving a grade of A = 25%

To find number of students that will receive a grade of A.

Solution:

In order to find the number of students that will receive a grade of A, we will find the percentage students receiving A grade of the total number of the student.

Number of students receiving A grade = $25\%\ of\textrm{ Total number of students}$

⇒ $25\%\ of\ 300$

Writing 25% as fraction and multiplying.

⇒ $\frac{25}{100}\times 300$

⇒ $\frac{7500}{100}$

⇒ $75$

∴ Total number of students receiving A grade = 75 (Answer)
