Detailed Solution

Ravi wants to go to his friend’s birthday party, which is 20 km away from a taxi stand. He decides to take a taxi in order to reach the destination. He asked a taxi driver about the fare. The taxi driver said that Rs 50 is the fixed amount and he charges Rs 16 per km.  Then the amount Ravi needs to pay to the taxi driver is Rs 370.
Given the distance from taxi stand to Ravi’s friend birthday party = 20km.
The taxi charge per km = Rs 16 and the fixed amount is Rs 50.
Let x be the distance Ravi wants to travel and y be the total fare.
The equation will be, y=50+16x  .
We know x=20  . Substitute the x value,
y=50+16x y=50+16×20 y=50+320 y=Rs370  
Hence, the total fare required is Rs 370.
