To estimate total purchase, the owner needs to know the total distance his taxis will travel next yr, the cost of a gallon of fuel and fuel millage of taxis. The owner has been provided with first two figures i.e distance estimate and cost of a gallon of fuel.

He measures and recorded and recorded the millage into (mile/gallons) for 15 taxis
