A three-wheeler scooter charges Rs 15 for first kilometre and Rs 8 each for every subsequent kilometre. For a distance of x km, an amount of Rs y is paid. Write the linear equation representing the above information.
Charges for the first kilometer = Rs 15
Charges for every subsequent kilometer = Rs 8
Distance = x km
and total amount = Rs y
∴ Linear equation will be 15+(x−1)×8=y⇒ 15+8x−8=y⇒ 7+8x=y∴ y=8x+7
