7 Car A uses petrol at the rate of 4.8L/100 km, whereas car B uses it at a rate of 10L/100 km. What will the difference in petrol costs be in a year in which both
cars travel 30000 km, if the petrol costs on average $1.45/L?

Step-by-step explanation:

30,000 km × (4.8 L / 100 km) × ($1.45 / L) = $2088

30,000 km × (10 L / 100 km) × ($1.45 / L) = $4350

The difference is $4350 − $2088 = $2262.
