Question

There are 40 nickels in every standard coin roll. What is the constant of proportionality?(Numbers only) Write an equation to represent this situation, in the form y=kx

Answer 1

Answer:

The answer is "40 nickels/standard coins"

Step-by-step explanation:

The ratio of 40 nickels/standard coins is constant, that is 1 roll with coins per 40 nickels, that's why the equation is y = 40 $\frac{nickels}{standard \ coins}$
