Answer 1

Dollars per gallon, because the dependent quantity is the dollars.

Explanation:

The most appropriate unit to describe the rate of the cost of gasoline is :

Dollars per gallon, because the dependent quantity is the dollars.

Dollars is the dependent quantity because it depend on the gallons of gas we have pumped.

A dependent variable is one, who depends on other entities. If the value of one entity changes, the value of the dependent variable also changes.

Like in this case, as the number of gallons increases, the amount of dollars increases.
