- Redo Exercise 5, assuming that the house blend contains 300 grams of Colombian beans, 50 grams of Kenyan beans, and 150 grams of French roast beans and the gourmet blend contains 100 grams of Colombian beans, 350 grams of Kenyan beans, and 50 grams of French roast beans. This time the merchant has on hand 30 kilograms of Colombian beans, 15 kilograms of Kenyan beans, and 15 kilograms of French roast beans. Suppose one bag of the house blend produces a profit of $0.50, one bag of the special blend produces a profit of $1.50, and one bag of the gourmet blend produces a profit of $2.00. How many bags of each type should the merchant prepare if he wants to use up all of the beans and maximize his profit? What is the maximum profit?In a study of the influence of financial institutions on bond interest rates in a certain country, quarterly data over a period of 12 years were analyzed. The postulated model was y¡ = Bo + B₁×₁¡ + B₂X2; + &¡, where y; is the change over the quarter in the bond interest rates, X₁₁ is the change over the quarter in bond purchases by financial institutions, and X2i is the change over the quarter in bond sales by financial institutions. The estimated regression coefficients are b₁ = 0.057 and b₂ = -0.033. Interpret these estimates. What is the correct interpretation of the coefficient estimates? Select the correct choice below and, if necessary, fill in the answer boxes within your choice. A. Each percent increase in the bond interest rates leads to a change in the estimated amount of bonds purchased by financial institutions by and a decrease in bond sales by financial institutions by. B. Each additional bond purchased by financial institutions leads to a change in the estimated bond…2. AMBK Company manufactures furniture such as sofas and tables. In their current inven- tory, a total of 48 planks of wood are left. Each sofa needs four planks of wood to be made while each table needs two planks of wood to be made. The company earns a profit of hundred pesos where P(x, y) = 12xy for selling a units of sofas and y units of tables. With their current inventory of woods, how many sofas and tables are needed to be produced to maximize their profit? (Use the Lagrange method of optimization.)
