Verified Answer
The taxi charges in a city consist of a fixed charge together with the...
Let the fixed cost be F, and the variable cost be V /km.
For a distance of 20 km, we have
205 = F + V(20)
For 25 km, we have
255 = F + V(25)
Subtracting the first equation from the second and hence eliminating F, we have
5V = 50
⇒ V = 10
Thus, F = 5
Therefore, to cover a distance of 50 km, we have
Charges = 5 + 10(50) = 505
