=+◗ Twenty trucks could be purchased, each with a capacity of 20 cubic metres. Each truck would cost $50000. The trucks consume 12 litres per 100 km driven; 400000 km (per truck) would be driven per annum to make the deliveries. The annual maintenance, registration and insurance is $1500 per truck. The trucks have an effective life of 400000 km, with a zero residual value.
