Concept explainers
Use the elimination method in Exercises 55 – 58 to find an equilibrium point for the described supply-demand situation. You may assume that the supply and demand equations are both linear.
Supply and demand-used books. A bookstore buys and sells used textbooks. For a current sociology text, it has found that if it pays an average price of $30 for each used book, it will be able to buy 60 texts for resale and will have 95 customers who are willing to buy the texts after markup. If it pays $42 per used text, it will be able to buy 120 texts but will be able to sell only 50 of them. What price should it offer for the used texts in order to sell all that it buys?

- In Exercises 7-10, find a linear equation that has the same solution set as the given equation (possibly with some restrictions on the variables). 2x+y=73yarrow_forwardRedo 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?arrow_forward23. Consider a simple economy with just two industries: farming and manufacturing. Farming consumes 1/2 of the food and 1/3 of the manufactured goods. Manufacturing consumes 1/2 of the food and 2/3 of the manufactured goods. Assuming the economy is closed and in equilibrium, find the relative outputs of the farming and manufacturing industries.arrow_forward
