1: A manufacturer has a monthly supply of 80 000 pounds of a raw material used in making four products. The number of pounds required to manufacture a unit of each product equals 16 , 10 , 12 , and 8 , respectively. If x1 , x2 , x3 , and x4 equal the number of units produced of each product: 1. Define the equation whose solution set includes the possible combinations of the four products which would exhaust the monthly supply of the raw material. 2. What is the maximum amount which could be made of each product if only one product is produced and the supply of raw material is the only limiting constraint? b) For correction purpose Please, don't use this area Given the following stem and leaf display stem leaf 1 0 2 3 6 9 3 3 4 7 8 4 0 2 5 5 2 2 3 7 9 6 1 3 4 Determine the original data. c) Given the following sample data of 30 students
