Question

The car rental charges in a city comprises of a fixed charge together with the charge for the distance covered for each km. For a journey of 13 km, the charge paid is Rs. 96 and for a journey of 18 km, the charge paid is Rs. 131.
What does the person pay for travelling 25 km ?​

Answer 1

Answer:

For 25 km the charge paid would be Rs.180

Step-by-step explanation:

Let the charge for each km be x

and the fixed charge be y

therefore ,

x+18y=131

x+13y=96

by subtracting the equations we get ,

5y=35

y=7

by putting the values in second equation  

x+13*7=96

x=5

therefore for 25 km,

5+25*7

=5+175

=Rs.180
