Answer:
More student's prefer PE. See numbers below.
Step-by-step explanation:
Remark
You have to assume that the choices are mutually exclusive. That means that if a student likes PE he can't choose Social Studies. If he likes Social Studies best then he doesn't like PE best.
Begin by finding out what 75% of the students are.
75/100 * 20 = 75 * 20/100 = 1500/100 = 15.
Fifteen students prefer PE. Only 4 like Social Studies.
15 > 4
1. anything 5 below
2. anything below 9
3.anything below 16
4. anything above 6
Let the number she mailed yesterday be x.
She mailed 8 more today. Total = x + 8
if she mailed 52 in all.
x + 8 = 52
x = 52 - 8
x = 44
So she mailed 44 cards yesterday.
