Question

Mrs. Ruan provides bike renting services. She charges $5 dollars per hour plus a one-time fee of $10. Is

this relationship a proportional relationship or a non-proportional relationship?
A Proportional
B Non-Proportional​

Answer 1

A

Explanation:

Let the number of hours spent by a costumer be X

As X increases the number of hours increases

It's a proportional relationship. If we draw the graph we see it .

Answer 2

B. Non-Proportional

Explanation:

Any proportional relationship will include (0, 0) as a possible (input, output) pair. Here, the one-time fee of $10 means the output for 0 hours is not 0, but is 10. That is (0, 10) is a pair in the relationship, not (0, 0).

The relationship is non-proportional.
