A manufacturer of plastics is planning to blend a new product from four chemical compounds. These compounds are mainly composed of three elements: A, B, and C. The composition and unit cost of these chemicals are shown in the following table: CHEMICAL COMPOUND 1 2 3 4
Percentage A 35 15 35 25
Percentage B 20 65 35 40
Percentage C 40 15 25 30
Cost/kilogram 20 30 20 15
The new product consists of 25 percent element A, at least 35 percent element B, and at least 20 percent element C. Owing to side effects of compounds 1 and 2, they must not exceed 25 percent and 30 percent, respectively, of the content of the new product.
A) Formulate he problem of finding the least costly way of blending as a linear program.
B) Calculate the optimum value for objective function and optimal value for each one of the decision variables used in your model, by using M. S EXCEL solver.

Magic realm, inc., has developed a new fantasy board game. the company sold 15,000 games last year at a selling price of $20 per game. fixed expenses associated with the game total $182,000 per year, and variable expenses are $6 per game. production of the game is entrusted to a printing contractor. variable expenses consist mostly of payments to this contractor.required: 1-a. prepare a contribution format income statement for the game last year.1-b. compute the degree of operating leverage.2. management is confident that the company can sell 58,880 games next year (an increase of 12,880 games, or 28%, over last year). given this assumption: a. what is the expected percentage increase in net operating income for next year? b. what is the expected amount of net operating income for next year? (do not prepare an income statement; use the degree of operating leverage to compute your answer.)

At the end of the current year, accounts receivable has a balance of $550,000; allowance for doubtful accounts has a credit balance of $5,500; and sales for the year total $2,500,000. an analysis of receivables estimates uncollectible receivables as $25,000. determine the net realizable value of accounts receivable after adjustment. (hint: determine the amount of the adjusting entry for bad debt expense and the adjusted balance of allowance of doubtful accounts.)

Inventory by three methods; cost of goods sold the units of an item available for sale during the year were as follows: jan. 1 inventory 20 units at $1,800 may 15 purchase 31 units at $1,950 aug. 7 purchase 13 units at $2,040 nov. 20 purchase 16 units at $2,100 there are 18 units of the item in the physical inventory at december 31. determine the cost of ending inventory and the cost of goods sold by three methods, presenting your answers in the following form: round your final answers to the nearest dollar. cost inventory method ending inventory cost of goods sold a. first-in, first-out method $ $ b. last-in, first-out method $ $ c. weighted average cost method $ $
