Enter an equation to represent the cost (C) of shipping a package based on its mass in pounds (p).

​

Answer 1

Answer:

C = 4p

Step-by-step explanation:

Because it starts at 0 pounds costs 0 dollars, we know it starts at the origin and has no y-intercept. Because it rises up 20 dollars for every 5 pounds, we can use rise/run to do 20/5 to get an increase of 4 dollars per pound.
