The cost of 10eggs is Rs.8
Thus the cost of one eg,
Let x represents the number of eggs and y represents the total cost of x eggs.
Thus the linear equation represents this transaction is
Let us observe the following graph:
The points P and Q represent the points when the number of eggs are 15 and 16 respectively.
Draw perpendiculars, PM and QN to y-axis.
Thus, M and N represent the total cost of 15 and 16 eggs respectively.
By reading the graph, the cost of 15 eggs is Rs.12
And the cost of 16 eggs is Rs.12.8
