Gina surveyed students about their lunch time preference. Out of 50 students, 20 prefer eating lunch at 11:00am, 15 prefer eating at 11:15a.m., 10 prefer eating at 11:30a.m. , and 5 have no preference. Based on the information, what is the probability that a student chosen at random has no lunch time preference?
60 coins
30%=pennies
100-30=70% =not pennies
percent menas parts out of 100 so
70%=70/100=7/20=0.7
so we want to find 70% of 60
'of' can be translated to as multiply
0.7 times 60=42
42 coins=not pennies
Answer:4x
Step-by-step explanation:
Answer:
$156.25
Step-by-step explanation:
A good strategy in my opinion is the "finders" strategy
50$ = 32%
x = 100%
First Multiply 100 by 50
100 x 50 = 5,000
Then Divide 5,000 with 32
5,000/32 = $156.25
If you want to check, then...
156.25 x 32 = 5,000
<em />
<em>x = $156.25</em>
Hope this helps!
