Answer:
20
Explanation:
The percentage of students gaining an A or B = 38 + 25 = 63%
Calculate 63% of the 32 students
63% = = 0.63, hence
0.63 × 32 ≈ 20
20 students
The percentage of students scoring a B or A = 38 + 25 = 63%
We need to evaluate 63% of the 32 students who did the test
(63/100)*32 = 20.16
Therefore, approximately 20 students earned a B or higher
