Zoc Princeton is committed to sustainable operations for EcoCurls and is looking at replacing her mobile hairdressing van with another van that is more fuel efficient. Most trips to customers are within a 5 kilometre radius of EcoCurls and the driver must have easy access to the back of the vehicle where the hair care products are stored. Zoe has provided the following information for the two vehicles that she is considering: White Giselle This vehicle is a mini van, has a 70 litre fuel tank and is able to travel 550 kilometres on a full tank. It also has a side sliding door and free servicing for the first 12,000 kilometres. Price S18,500. Green Cornet This vehicle is a hatchback with a 60 litre fuel tank and is able to travel 400 kilometres on a full tank. It comes with 12 month free servicing and roadside assist. Price $18,700. Required: (1) Calculate the eco-efficiency ratios for the White Giselle and the Green Cornet and explain which vehicle is more eco-efficient. (4marks) (2) If the fuel price is $1.65 per litre what is the saving per 100 kms between the White Giselle and the Green Cornet? (2marks)
