The makers of the car shown in Fig. 8.5 plan to market it in Europe. If the car covers 120,000 miles \((193,000 \mathrm{~km})\) over its life and consumes on average 9.5 litres per \(100 \mathrm{~km}\). Petrol in the Europe costs \(€ 1.3\) per litre ( \(\$ 1.5\) per litre), so the life cost for fuel is \(\$ 27,500\). The car, when loaded, weighs \(2315 \mathrm{~kg}\). If the petrol consumption is directly proportional to the weight, what is the value of reducing the weight of the car by \(1 \mathrm{~kg}\) ?
