# The taxi fare in

Fixed amount = Rs 50

Charges for 1 km = Rs 16

Charges for 2 km = Rs 16 × 2 = Rs 32

Charges for x km = Rs 16 × x = Rs 16x

Total fare = y = Fixed amount + Charges for x km

= Rs 50 + Rs 16x

Therefore, the linear equation is, y = 50 + 16x

Now, to find the total fare for 20 kms, put x = 20 in y = 50 + 16x

y = 50 + 16 × 20

y = 50 + 320

y = 370

Therefore, the total fare for 20 km is Rs 370
