Select the correct answer.
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?
A.
1/355
B.
1/177.5
C.
177.5
D.
355
A. 1/355
To find the constant of proportionality (r to m) in the given equation r = 355m, we can compare it with the general form of a proportional relationship, which is r = km, where k represents the constant of proportionality.
By comparing the two equations, we can see that the constant of proportionality (r to m) in the given equation is 355.
Therefore, the correct answer is:
D. 355
