: 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:
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
