Solve This:
$$\begin{gathered} The parking charges \left(per hour\right) for vehicles in a parking Rs 20 for the first two hour and Rs 10 \\ for subsequent hours \left(Where x\ge 2\right) and total parking charges as Rs y. Write a linear equation \\ to express the above relation and draw its graph. \end{gathered}$$

Dear Student,

Please find below the solution to the asked query:

Given : Parking charges for vehicles in a parking is Rs. 20 for first two hour and Rs . 10  for subsequent 

And total parking charges  =  y 

So,

y  =  20 + 10 ( x -  2 ) ,

y  =  20 + 10 x  - 20 ,

y  = 10 x                                                        ( Ans )


We form a table for above equation for different values of ' x ' and ' y '  , As :
 

y  = 10 x
x ( Given : x $\ge$ 2 )	y
2	20
4	40
5	50
8	80
10	10

Now we draw required graph from above points , As :
