Taking x to be the number of plots used for Type X and y to be the number of plots used for Type Y, write down 3 inequalities in x and y for the following case:

A farmer has plots for planting with two kinds of fruittrees, Type X and Type Y. Type X can only be planted 80 in a plot and Type Y only 40 in a plot. He has just enough workers who can plant at the most 640 plants during the time available.

He intends to plant atleast as many plots with Type X as with Type Y.

The number of plots used for Type X is x and the number of plots used for Type Y is y.

80 fruit trees of Type X can be plotted in a plot while only 40 of Type Y can be planted in a plot.

The number of workers with the farmer can plant a maximum of 640 trees.

This gives 80*x + 40*y <= 640

=> **2x + y <= 16**

Also, 80*x <= 640

=> **x <= 8**

and 40*y <= 640

=> **y <= 16**
