Answer:

f(5)=15*5=75

Step-by-step explanation:

The cost of a notebook in a bookshop is Rs. 15.Form a linear equation with x-representing the number of notebooks and y-representing the total cost (in Rs.) and draw a graph . From the graph,find the total cost if 5 notebooks are purchased.

..................

y = 15x

{graph(400,400,-10,10,-10,200,15x)}

------

f(5) = 15*5 = 75...
