A community has two waste sources S1 and S2 having option todispose waste at either
landfill LF1 at $4/tonne, or LF2 at $6/tonne. S1 and S2 generatewaste at 150 tonnes/week and 300
tonnes/week, respectively, and transportation costs are $8/tonne(S1 to LF1), $7/tonne (S1 to LF2),
$6/tonne (S2 to LF1), and $5/tonne (S2 to LF2). (A) (2 points) Atwhich landfills should S1 and S2 dispose
the wastes to minimize total cost of transportation and disposal?(B) (4 points) What are the minimum
costs of transportation and disposal ($/week) for S1, S2, and totalcommunity? (C) (4 points) What are
the minimum transportation costs ($/week) for S1, S2, and totalcommunity?
