Solution
To solve this problem, we first need to calculate how much petrol Keb uses in a year with his old vehicle and how much it costs him. Then we calculate how much petrol he would use with a more fuel-efficient vehicle and how much it would cost him. The difference between these two amounts is how much he would save.
