Question

Tammy rents an apartment close to her school campus. The amount that she spends on rent is given by the equation r = 355m, where r is the amount spent on rent and m is the number of months she stays in the apartment. What is the constant of proportionality (r to m) for this proportional relationship?

Answer 1

The constant of proportionality k is given by y = kx.

In your equation, it would be r = km.
