Answer:
C= 25n+100
Step-by-step explanation:
Let's see what's in the graph : 
- the image of 4 is 200 C(4)=200 
- C(2)= 150 
let m be the slope of this function : 
- m=  =25 =25
The first value in the graph is 100 wich is c(0)=100
- so the equation is : c=25n+100

reduced:
7.45 dollars /2.5 pounds 
GCF=0.5
7.45/0.5=14.9$
2.5/0.5=5
unit rate:
$14.9/5 pounds
 
        
             
        
        
        
Neither. A factor is when a number fits in to another number. For example, 6, 2, 12 and 1 are all factors of 12. A multiple again is when a number fits into a number but in a different way (2,4,6,8,10,12,14... are all multiples or 2)
24 and 36 both have common factors (12) which means that 12 is a factor of both of those numbers.
