Which math function describes the following situation?
the distance a car travels, which depends on how full the gas tank is, is 89 miles.
a. amount of gasoline(distance) < 89
b. distance(amount of gasoline) < 89
c. distance(amount of gasoline) = 89
d. amount of gasoline(distance) = 89

This is the concept of inequality;
We are told that the distance a car travels depends on how full gas tank is, this means that the car will travel until the point when gasoline is finished. Thus,
This mean that if the if the distance is given by the function f(x), x will be the gasoline since it is the dependent variable, liters this in other words can be written as (if the tank holds 89 ):

f(x)=distance(gasoline)<89

thus the correct answer will be:

B] Distance (amount of gasoline) <  89
