Answer:
The answer to your question is 200 visitors went to screen 1
125 visitors went to screen 2
175 visitors went to screen 3
Step-by-step explanation:
Data
3 screens
total number of visitors = 500
40% screen 1
25% screen 2
rest screen 3
Process
1.- Calculate the 40% of 500
500 visitors ------------------- 100%
x ------------------- 40%
x = (40 x 500) / 100
x = 20000/100
x = 200 visitors
2.- Calculate the 25% of 500
500 visitors ------------------- 100%
x ------------------- 25%
x = (25 x 500) / 100
x = 12500/100
x = 125
3.- Calculate the number of visitors to screen 3
500 - 200 - 125
175
Answer:
x = 2
Step-by-step explanation:
6 ÷ 2 = 3
8 ÷ 2 = 4
4 ÷ 2 = 2
9+9+2=20
9+8+3=20
9+7+4=20
9+6+5=20
(These ones are kin of repeated but in a different order:)
9+5+6=20
9+4+7=20
9+3+8=20
9+2+9=20
I believe that would be the last choice, because it is not impossible that someone without contacts or glasses would be chosen. And it is a fairly similar chance that someone with glasses or with contacts will be chosen. Hope this helps! :)
