A) Using a scale of 2 cm to represent 5 calculators on the x-axis and 2 cm to represent 10 folders on the y-axis, draw the graph of the
lines associated with the inequalities in i, il, and liabove.
b) Identify, by shading, the region which satisfies all three inequalities
The profit on each calculator is $6 and on each folder is $2.
iv. Write an expression in x and y for the total profit, P.
Using your graph
Write down the coordinates of the vertices of the shaded
region
VI
Calculate the maximum profit

Me because some of question i don’t understand
