We need to find how many students have at least one social media account.
We know that there are 120 students in the class.
We also know that there are 65% of students that have at least one social media account.
To find your answer, would multiply 120 by 0.65:
120 · 0.65 = 78
This means that 78 of the students has at least one social media account.
Answer:
78 students
Answer:
a) 68
b)60

0.85 * 80 = 68
b) let x be the unknown number.
35% = 0.35
0.35x = 21
x = 60
