Proportional or non-proportional?

Babysitting problem


Carla had a babysitting business. She charges her customers $4 for every hour that she works. Any time she baby-sits after 7pm, she charges an additional $3 fee to her customers. Make a graph and chart showing if a customer asks her to baby-sit after 7pm.



Proportional or non-proportional?

This is a non-propornional problem. This is a non-proportional problem because the numbers in the chart are not multiples of any number. This is why this is a non-proportional problem.
