Question

: A three-wheeler scooter charges Rs. 15 for the first kilometre and Rs. 8 each for every subsequent kilometre. For a distance of x km, an amount of Rs. y is paid. Then the linear equation representing the above situation is

a.8x - y + 7 = 0
b.x - 8y + 7 = 0
c.x - 8y - 7 = 0
d.8x - y - 7 = 0

Answer 1

Answer:

a.8x-y+7=0

Step-by-step explanation:

The scooter charges Rs. 15 for first kilometer and Rs. 8 each for every subsequent kilometer.

Distance traveled =x km

So, Rs. 15 is paid for first kilometer.

And Rs. 8 each for every subsequent kilometer for the rest x−1 km

Total amount paid =15+8(x−1)

y=15+8x−8

y=8x+7

Answer 2

Step-by-step explanation:

15+8(x-1)=y

15+8x-8=y.

=>8x-y+7=0

option a is your answer.
