A company manufactures paring knives and pocket knives. Each paring knife requires 3 labor-hours, 7 units of steel,and 4 units of wood. Each pocket knife requires 6 labor-hours, 5 units of steel, and 3 units of wood. The profit on eachparing knife is $3, and the profit on each pocket knife is $5. Each day the company has available 102 labor-hours, 157units of steel, and 123 units of wood. Suppose that the number of labor-hours that are available each day is increasedby h. For what values of h will a change of h labor-hours not change the shadow price of labor?The shadow price of labor will not change for shs.(Simplify your answers.)

A game company is developing two new games, a board game, and a mechanical game. Each board game requires 1/2 hr to manufacture, 1/2 hr to assemble, and 1/2 to inspect and package. In given week there are 40 hours available for manufacturing, 32 hours available for assembly, and 18 hours available for inspection and packaging. Suppose the profit on each game is $10 and the profit on each mechanical game is $15. How many of each game should be produced each week for maximum profit?
A carpenter builds bookshelves and tables for a living. Each bookshelf takes one box of screws, two 2 ✕ 4's, and three sheets of plywood to make. Each table takes two boxes of screws, two 2 ✕ 4's, and four sheets of plywood. The carpenter has 55 boxes of screws, 70 2 ✕ 4's, and 115 sheets of plywood on hand. In order to maximize their profit using these materials on hand, the carpenter has determined that they must build 10 shelves and 20 tables. How many of each of the materials (boxes of screws, 2 ✕ 4's, and sheets of plywood) are leftover, when the carpenter builds 10 shelves and 20 tables? The carpenter has _ boxes of screws, _ 2 ✕ 4's, and _ sheets of plywood leftover.
A company produces 3 products. Each unit of product 1, 2, and 3 generate a profit of GH₵10, GH₵12, and GH₵12 respectively. Each product has to go through a manufacturing, assembly, and testing phase.

A manufacturer produces two models of toy airplanes. It takes the manufacturer 32 minutes to assemble model A and 8 minutes to package it. It takes the manufacturer 20 minutes to assemble model B and 10 minutes to package it. In a given week, the total available time for assembling is 3200 minutes, and the total available time for packaging is 960 minutes. Model A earns a profit of $10 for each unit sold and model B earns a profit of $8 for each unit sold. Assuming the manufacturer is able to sell as many models as it makes, how many units of each model should be produced to maximize the profit for the given week?
