• A farmer in Georgia has a 100-acre farm on which to plant watermelons and cantaloupes. Every acre planted with watermelons requires 50 gallons of water per day and must be prepared for planting with 20 pounds of fertilizer. Every acre planted with cantaloupes requires 75 gallons of water per day and must be prepared with for planting with 15 pounds of fertilizer. The farmer estimates that it will take 2 hours of labor to harvest each acre planted with watermelons and 2.5 hours of labor for each acre planted with cantaloupes. He believes that watermelons will sell for about $3 each, and cantaloupes will sell for about $1 each. Every acre planted with watermelons is expected to yield 90 salable units. Every acre planted with cantaloupes is expected to yield 300 salable units. The farmer can pump 6,000 gallons of water per day for irrigation purposes from a shallow well. He can buy as much fertilizer as he needs at a cost of $10 per 50-pound bag. Finally, the farmer can hire laborers to the harvest the fields at a rate of $5 per hour. If the farmer sells all the watermelons and cantaloupes he produces, how many acres of each crop should the farmer plant to maximize profits?

- THIS IS WHAT I HAVE SO FAR: (what I don't know is how to show the Labor and Fertilizersince there are no restraints its just a cost per hour or 50 pound bag?)

Watermelon = x MAX 3(90x)+ 1(300y)

Cantaloupe = y

1x+1y 100 acres of farm land

50x+ 75y 6,000 gal of water per day

20x + 15y = fertilizer at $10 per 50 pounds

2x + 2.5y = hours of labour at $5 per hour
