You can put this solution on YOUR website!
Let +x+ = the maximum
number of 4 pound bags
of apples the cafeteria can buy.
-------
+y+ is the maximum
number of 7 pound bags of
apples the cafeteria can buy
-------
+4x+%2B+7y+%3C=+28+
+7y+%3C=+-4x+%2B+28+
+y+%3C=+-%284%2F7%29%2Ax+%2B+4+
Here's the graph. All the possible solutions
lie on the line and under the line
and bounded by the
x and y axes
+graph%28+400%2C+400%2C+-2%2C+10%2C+-2%2C+10%2C+-%284%2F7%29%2Ax+%2B+4+%29+
