A three-wheeler scooter charges 15rupees for first km and 8rupees for every subsequent km. For a distance of x km, an amount of y rupees is paid. Write the linear equation representing the above information

Solution

Total distance travelled = x km.
Charge for 1st km = Rs 15.
Charge for next (x-1) km is Rs 8 per km
So charge for next (x-1) km = 8(x-1) = Rs 8x-8
So total charges for x km = 15 +8x-8 = 8x + 7
So y = 8x + 7 is the equation
