Answer Details

The equation Qs = 25 + 0.25P represents the relationship between the quantity supplied (Qs) of petrol and its price (P). When the price per litre is N30, we can substitute this value into the equation to find the quantity supplied: Qs = 25 + 0.25 * 30 Qs = 25 + 7.5 Qs = 32.5 So, the quantity supplied of petrol when the price per litre is N30 is 32.5 litres.
