A company makes four products that have the following
characteristics: Product A sells for $50 but needs $10 of materials and
$15 of labor to produce; Product B sells for $75 but needs $30 of
materials and $15 of labor to produce; Product C sells for $100 but
needs $50 of materials and $30 of labor to produce; Product D sells for
$150 but needs $75 of materials and $40 of labor to produce. The
processing requirements for each product on each of the four
machines are shown in the table.
