Auto's in Bangalore have a fixed charge of ₹25 for first 2 km and then an additional charge of ₹13 per additional km. If x represents the distance travelled, the expression for total charge is ______.
13x−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 chrage + Fixed charge
= 13(x−2) + 25
= 13x−1
