A refinery blends three petroleum components into two grades of gasoline – regular and premium. The maximum quantities available of each component and the cost per barrel are as follows: Component Max Barrels Available/Day Cost/Barrel
1 5,000 9
2 2,400 7
3 4,000 12
4 1,500 6
To ensure that each gasoline grade retains certain essential characteristics, the refinery has put limits on the percentage of the components in each blend. The limits as well as the selling prices for the various grades are as follows:
Grade Component Specifications Selling Price/Barrel
Regular Not less than 40% of 1
Not more than 20% of 2
Not less than 30% of 3 $12
Premium Not less than 40% of 3 $18
Diesel Not more than 50% of 2
Not less than 10% of 1 $10
The refinery wants to produce at least 3000 barrels each of super and premium and 4000 barrels of regular. Management wishes to determine the optimal mix of the four components that will maximize profit.
A. Formulate a linear programming model for this problem.
B. Solve the model by using the Excel Solver.

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.

anyone below or above ambitious can tell you. so crowns mean brainliest. getting brainliest means your answer needs a good explanation and the person asking the question can understand your answer easily. so say there's a multiple choice question. you don't just want to say your answer is a, hope it . provide evidence and reasoning so that they know that that is the correct answer. a good explanation should have evidence, good reasoning, and your opinion on why you picked that. you don't want to look up their question on the internet and see if you can answer it. pick questions that you 100% know the answer to, so than that way you can provide a better explanation.

best of luck,

all you have to do is give a good answer with details and the answer has to be understandable and then they will most likely give you the brainliest answer.
