Question

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.

Answer 1

Charges for the first kilometer = Rs 15

Charges for every subsequent kilometer = Rs 8

Distance = x km

and total amount = Rs y

$\therefore$ Linear equation will be $15+(x-1)\times 8=y\Rightarrow 15+8x-8=y\Rightarrow 7+8x=y\therefore y=8x+7$
