Big idea: Relations and Functions

PROGRAMMING AND ASSESMENT IN MATHEMATICS 9 Big idea: Relations and Functions Mathematics Big Idea The development of mathematical knowledge is an integration of various concepts. Children develop the concepts through different approaches. However, the role of the teacher in the development of mathematical concept cannot and should not be overlooked.

Decision Analysis (m)

QUESTION 1 How many shops of each type should Super Malls have in the mall in order to maximize rent? Derive a Linear Program that solves the problem. You do not need to solve the problem. Shop type Space (sq ft) Minimum # Maximum # Rent Department 2,000 1 3

Decision Analysis (h)

From the given information, the objective of SuperMalls is to maximize profit under the given constraints. Thus the linear equation can be developed as follows: Objective function: Maximise profit (revenue-Cost) Objective function: (30D + 8A + 20C+15B+10S)1000. Constraints: Total space hired ≤ Total Available space 2000D sq.ft + 500A sq.ft
