Find the equation that shows the relationship between the number of pens, p, and the total cost, c.
5

Number of Pens (p)
$3.95
$7.90
$11.85
$15.80
Cost (c)

c= 0.79p

Step-by-step explanation:

Divide each cost by the number of pens it have to find the constant change value.

3.95/5 = 0.79

7.90/10= 0 .79  

11.85/15 = 0.79

15.80 / 20 = 0.79

Since the constant change is 0.79  which means that for each pen it will cost you $0.79, then the equation will be  c= $0.79p  where c is the cost and p is the number of pens.
