Question

For every $50.00, Michael earns, he saves $5.. for the future. what is the constant of proportionality (k)?

Answer 1

Constant of proportionality is given by: y=kx oy $k=\frac{y}{x}$

So lets suppose y = 50 and x = 5 so k will be $\frac{50}{5}=10$

This 10 will remain constant. For every $50 Michael saves $5, for $100 he will save  $10 , for $150 he will save $15 and so on.

So this 'k' will be same for each value of x and y.
