Question -

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



Answer -

Charges for the first kilometer = тВ╣15
Charges for next 1 km = тВ╣8
Distance = x km
and total amount = тВ╣y
тИ┤ Linear equation will be,
15 + (x- 1) x 8 =y
тЗТ┬а 15 + 8x тАУ 8 = y
тЗТ┬а ┬а7 + 8x = y
тИ┤┬а y = 8x + 7
