The taxi fare in a city is as follows: For the first kilometre, the fare is Rs. 8 and the subsequent distance it is Rs. 5 per km. Taking the distance covered as x km and fare as Rs y, write a linear equation.
The correct option is D (y=3+5x)
Since, for the first 1,km fare=8
and further subsequent distance it is Rs.5 per km.
To find fare(y) for x km: first 1 km, we have to subtract from x,
So (x−1)km, it cost Rs.5 per each km.
So, Fare=(x−1)5
Now we can add 1km fare separately as follow:
Thus, total fare, y=5(x−1)+8=5x−5+8=3+5x
