Three orchards supply crates of ora

Three orchards supply crates of oranges to four retailers. The daily demand amounts at
the four retailers are 150,150,400, and 100 crates, respectively. Supplies at the three orchards
are dictated by available regular labor and are estimated at 150,200, and 250
crates daily. However, both orchards 1 and 2 have indicated that they could supply more
crates, if necessary, by using overtime labor. Orchard 3 does not offer this option.The
transportation costs per crate from the orchards to the retailers are given in Table 5.8.
