Question

7. The taxi fare in a twon is Rs 10 for the first kilometre and Rs 6 per km for the subsequent distance. Taking the distance as �x� km and total fare as Rs. y, write a linear equation for this information, what will be the total fare for 15 km?

Answer 1

Answer:

Given,

Taxi fare for first kilometer = Rs. 10

Taxi fare for subsequent distance = Rs. 6

Total distance covered = x

Total fare = y

Since the fare for first kilometer = Rs. 10

According to problem,

Fare for (x - 1) kilometer = 6(x-1)

So, the total fare = 6(x-1) + 10

y = 6(x-1) + 10

y = 6x - 6 + 10

y = 6x + 4

Hence, y = 6x + 4 is the required linear equation.
