4. Which labor and material resources are completely used? 5. What would be the impact on the optimal solution if the demand for all three products were decreased by 10% each? 6. What would be the impact on the optimal solution if hand cream could be subcontracted at a cost of $35/carton?

3. Suppose you have a 300 gallon tank filled to the top with brine that begins with 50 lbs of salt in it. If you begin draining the well-mixed brine from the bottom of the tank at a rate of 15 gallons per minute while. If you want the tank to have 10 lbs of salt in it when it gets down to 100 gallons, at what rate should you be pouring in brine with a 1 lb of salt per 10 gallons consistency?

3. Half-lives. Glyphosate is the active ingredient in some herbicides (weed killers) such as RoundupⓇ, Rodeo®, and Accord®, and is typically sprayed onto agricultural fields and forests. When glyphosate lands on plants, it is quickly absorbed through the leaves; in high enough concentration, glyphosate will kill a plant in 24 hours. Glyphosate that lands on soil eventually breaks down, although it can kill microorganisms that are beneficial to the soil. The average half-life of glyphosate in soil is 40 days-sometimes more or less depending on soil conditions. Recommended application rates of glyphosate vary from 0.3 to 4.0 pounds per acre." [9 pts total] a. With a half-life of 40 days, determine the daily decay rate of glyphosate in soils. Report 2 significant figures and include units. b. Suppose that 4 pounds of glyphosate are applied to a 1-acre agricultural field, with 1 pound landing on the soil. Compute the number of days until the glyphosate in the soil breaks down to 0.25…
