Answer 1

Answer:

y = 10x + 10 ; Rs 60

Step-by-step explanation:

Given, parking charges for the first two hours = ₹30

and for subsequent hours = ₹ 10

Total parking time = xh and total charges = ₹y

Then, according to the given condition,

30 + 10(x-2) = y=> 30 + 10x -20 = y

=>10x + 10-y = 0

=>10x-y+10 = 0 (i)

which is the required linear equation in two variables.

It can also be written as

y = 10x + 10 ,…(i)

Now, for drawing the graph, we need atleast two solutions of the equation.

When x = 0, then y = 10(0) +10 = 10

When x = -1, then y = -10 + 10 = 0

When x = 1, then y = 10(1) + 10 = 20

Parking for five hours will take Rs60
