Question

The parking charges(per hour) for vehicles in Super Delhi Metro is Rs20 for the first 2 hours and Rs 10 for subsequent hours.Assume total parking time x hours ( where x>2) and total parking charges as Rs you. Write a linear equation in two variables
to express the above relation

Answer 1

Y=30+10x {x>2}
hope this helped !

Answer 2

Answer:

C = 10x, x > 2

Step-by-step explanation:

Hi,

Given that the parking charges( per hour) for vehicles

in Super Delhi Metro is Rs 20 for the first 2 hour.

Given that the parking charge is Rs 10 for subsequent

hours.

Assume total parking time = x hours

Let Total Parking Charges be represented by C,

Any linear function will be in the form

y = mx + k form,where m and k are constants

Since C and x form linear equation ,

C will be in the form

C = mx + k------------(1)

Given that if x = 2 hours, then C = Rs 20

SO, 20 = 2m + k------(2)

If x = 3 hrs, then C would be

Rs 20(Charge for 2 hours) + Rs 10 (Extra charge for subsequent

hour) = Rs 30

So, 30 = 3m + k---------(3),

Solving (2) and (3), we get

m = 10 and k = 0,

So, C = 10x

Hence, If x > 2, then the linear equation is

C = 10x.

Hope, it helps !
