Answer: D. 355
Step-by-step explanation:
Given : Tammy rents an apartment close to her school campus.
The amount that she spends on rent is given by the equation
[tex]r=355m[/tex], where is r(dependent variable) is the amount spent on rent and m(independent variable) is the number of months she stays in the apartment.
Since ,The constant of proportionality is the ratio between two directly proportional variables.
Thus, the constant of proportionality (r to m) for this proportional relationship (basically dependent variable to independent variable) :-
[tex]\dfrac{r}{m}=355[/tex]
Hence, the constant of proportionality (r to m) for this proportional relationship= 355
