Auto's in Bangalore have a fixed charge of Rs. 25 for first 2 km and then an additional charge of Rs. 13 per additional km. If x represents the distance travelled, the expression for total charge is ______.
The correct option is C13x−1
x represents the distance travelled. So, the distance applicable for additional charge is x−2.
∴ Total additional charge = 13(x−2)
Therefore total charge = Additional charge + Fixed charge
= 13(x−2) + 25
= 13x−1
