An advertising company offer three types of mediums: television, newspaper and radio. The cost for each medium with its audience coverage is given below, Television Newspaper Radio Cost per advertisement (S) 1500 k00 b00 Audience per advertisement 97,000 43,000 18,000 The company is capable of using a number of newspaper advertisement slots up to 9. Morcover, in order to balance the advertising among the three types of media, the total number of advertisements on radio should not occur more than 40% of total number of advertisement, and at least 9% of the total number of advertisements should occur on television. The weekly advertising budget is S19400. How many advertisements should be run in each of the thre types of media to maximize the total audience? If we assume the number of ads on each type of meduim as follows : T, N, R respectively Given the following Radio constrain 40T - 40N + mR 0 What is the value of m?

Enormous State University's Business School is buying computers. The school has two models from which to choose, the Pomegranate and the iZac. Each Pomegranate comes with 400 GB of memory and 80 TB of disk space; each iZac has 300 GB of memory and 100 TB of disk space. For reasons related to its accreditation the school would like to be able to say that it has a total of at least 41,000 GB of memory and at least 11,000 TB of disk space. If the Pomegranate and the iZac cost $3,000 each, how many of each should the school buy to keep the cost as low as possible? HINT [See Example 4.] (If an answer does not exist, enter DNE.) Pomegranate computers___________ iZac computers_________
Let's say there are two sectors of an economy, firms and households. Each household supplies labor to the firms. Households earn $100 per month, they spend $1 per mile to commute to work and they spend $50 on all other goods. Firms produce 1 ton of goods and earn $100 per month net profits on production, but must pay $10 per ton mile to ship its output to the port. All firms, residents use 1 acre of land. Calculate each sector's bid rent function. That is, what is each sector's ability to pay for a location as a function of distance to the center? How far from the center will land use change from business use to residential? Draw a graph of the sector's bid rent function as a function of distance from the center. Be sure to label the graph and describe the location of each sector.
Solve using LPP Simplex method don't use shortcuts from excel thankyou. A diet for a sick person must contain at least 4000 units of vitamins, 50 units of minerals and 1400 of calories. Two foods A and B are available at a cost of Rs. 4 and Rs. 3 per unit respectively. If one unit of A contains 200 units of vitamins 1 unit of mineral and 40 calories and one unit of food B contains 100 units of vitamins, 2 units of minerals and 40 calories, find by simplex method what combination of Foods be used to have least cost.

A system of 4 linear equations in 3 unknowns has no solutions. True FalseJustification:
Part1)An airplane carries water and medical kits to survivors of a natural disaster. The plane can carry a maximum payload of 80,000 pounds. Each container of water weighs 20 pounds, and each medical kit weighs 10 pounds.The cargo space holds a maximum of 6000 cubic feet of cargo. Graph these constraints on the grid provided, and write some units on the axes. Assume each container has a volume of 1 cubic foot. Part2)If each container of water serves 10 people and each medical kit aids 6 people, find the number of water containers and medical kits that could help the most people
