An lending library has fixed charge for the first three days and an additional charges for each day thereafter. John paid ₹27 for a book kept for seven days. If the fixed charges be₹x and subsequent per day charges be₹y,then write the linear equation representing the above information equation representing the above information and draw the graph of the same. From the graph find fixed charges for each day thereafter is ₹4. Find additional charges for each day thereafter if the fixed charges for the first three days of ₹7?
Answers
Answer:
Fixed charge of the book for 3 days = Rs. x
Subsequent per day charges = Rs. y
John kept the book for 7 days. he paid fixed charges for 3 days + charges per day for the next 4 days
in total he paid Rs. 27
Therefore
27 = x + 4y
or x+4y = 27
To plot the graph, we need two points
at y = 0, x = 27 and at x = -1, y = 7
The graph is attached
If the per day charge is Rs. 4 then y = 4
Corresponding to this y from graph x = 11
Therefore, the fixed charge is Rs. 11
