Nan uses two different biofuel mixtures in her diesel vehicle. both mixtures contain 20% ultra low sulfur diesel. mix 1 also contains 30% soybean oil and 50% waste cooking oil; mix 2 also contains 20% soybean oil and 60% animal fat. mix 1 generates 40 co emissions per gallon; mix 2 generates 74 co emissions per gallon. (note: units are shifted and scaled from actual units of grams per gallon for the purposes of this example.) nan wants to minimize the co emissions in 10 total gallons of fuel used in her vehicle. she has available 10 gallons of soybean oil, 4 gallons of waste cooking oil, and 5 gallons of animal fat. assuming there is no limit on ultra low sulfur diesel, formulate an lp model to determine how much of biodiesel mixtures 1 and 2 nan should use in her vehicle?

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
