Green Grass, Inc. just ran out of stock and suddenly has two emergency orders for

grass seed blends: one is for 1500 pounds of normal, the other for 2300 pounds of

special. At least each pound of normal should contain 60 percent annual seed, while

each pound of special should contain at least 70 percent perennial seed. Green Grass

has two input mixtures, A and B. Mixture A contains 80 percent perennial and 15

percent annual seed. Mixture B contains 70 percent annual and 25 percent perennial

seed. Mixture A costs 90 cents per pound and mixture B costs 50 cents per pound.
