I believe the best answer choice is going to be D because if you think about it, when you buy gas both the price and gallonage go up. Hope this helps..

The correct answer is:

D) The amount a person pays for gas compared with the number of gallons purchased

Explanation:

A constant rate of change means that for every x, y increases the same amount.

In the situation "The amount a person pays for gas compared with the number of gallons purchased
," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid.  Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount.  This means it has a constant rate of change.
