It take 160 ribbons to make 4 football mums. What is the constant of proportionality that relates the number of football mums made ,y, to the number of ribbons used, x? A.40 B.1/10 C.80 D.1/4

The constant of proportionality is

Step-by-step explanation:

We have a function that relate the number of football mums made to the number of ribbons needed, since they are proportional the function that relates the two variables is a linear function is shown below:

The constant of proportionality is the number, "a", that relates the two variables. It was state that 160 ribbons make 4 mums, therefore:

The constant of proportionality is
