The total cost of filling up your car with gas varies directly with the number of gallons of gasoline that you are purchasing. If a gallon of gas costs $2.25, how many gallons could you purchase for $18.
Inverse Variation
Example:
More men at work, less time taken to finish the work. Less men at work, more time is taken to finish the work. More speed, less time is taken to cover the same distance.
Joint Variation
Example:
the cost of busing students for each school trip varies with the number of students attending and the distance from the school.

Example:
the sales of a product may be directly proportional to the amount of money spent on advertising the product, but inversely proportional to the price of the product.
