The monthly cost of owning a car depends on the number of
kilometers it is driver. Taylor found that in May it cost her $500
to drive 800 km and it June it cost her $650 to drive 1400 km.
- Express the monthly Cost C as a function of the distance driven
d, assuming that a linear function is a suitable model.
- Use this function to predict the cost of driving 2000 km per
month.
- Find the derivative of the function with appropriate units.
What does the derivative of the function represent?
- Does it cost more to drive the car in December than it does in
August? Explain.
