Hey! I have a question regarding my calculus homework. This doesn't make much sense! If you could answer the question and provide steps of how you did it it would be much appreciated. Thanks. I provided two questions, answer both or just the first one.

1.The demand equation for a pesticide at a hardware store is given by , P=12 -1/3x ; 0 Less than or equal too X Less than equal too 30, where x is the number of gallons sold each week.Find the sales level,x , and the corresponding price,p , that will result in the maximum weekly revenue.Note: Include a sign chart for to determine the maximum.

2.A manufacturer of a specialized medical diagnostic piece of equipment uses the following models to predict its cost and revenue for a production level of xpieces of equipment each month: C(x)= x^3 -6x^2 +13x +15and , R(x)=28x where revenue and cost are measured in thousands of dollars.Find the production level that would maximize the manufacturer's monthly profit.Note: Include a sign chart for to determine the maximum.
