Answer:
Option B. $0.70 
Step-by-step explanation:
First day fine = $0.10
Second day fine (doubled or $0.30 which is lesser) 
= $0.10 + $0.10           [$0.10 is lesser than $0.30]
 = $0.20
Third day fine = $0.20 + $0.20           [ $0.20 is lesser than $0.30]
                        = $0.40
Fourth day fine = $0.40 + $0.30  = $0.70 
[$0.30 is cheaper than doubling the amount $0.40 + $0.40]
Therefore, the total fine for a book on the fourth day is $0.70
 
        
             
        
        
        
Answer:
Eight times the sum of a number and 2 is equal to 7.
times = multiply 
sum = ()
and = +
SO..
8(w + 2 ) = 7

Answer:
Median = 7
upper quartile = 10
lower quartile is 6
Step-by-step explanation:
The median is the middle line in the box
Median = 7
The upper quartile is the right line of the box
upper quartile = 10
The lower quartile is the left line of the box
lower quartile is 6
 
        
             
        
        
        
Answer: -2
Explanation:  On the image we can see it goes down 4 units and right 2. Giving us the slope 
Simplified that is -2 which is the slope of the line
