Given :
The fare for first five rides = ₹ 50
The fare after five rides = ₹ 7 per ride
The fare paid by the boy for X ride = ₹ Y
To find :
The linear equation for the information .
Solution :
For X rides ,
total fare paid = 50 {for first 5 rides} + 7 * ( X - 5 ) { total rides = X }
=> Y = 50 + 7 ( X - 5 )
=> Y = 50 + 7X - 35
=> Y = 7X + 15
The linear equation for the information is Y = 7X + 15 .
