Two day-to-day applications
What do you mean by iconic model?
physical representation of a real project on a different scale.
set of mathematical symbols and functions to represent
one set of properties is used to represent another set of properties.
A housewife wishes to mix two types of food F1 and F2 in such a way that the vitamin contents of the mixture contain at least 8 units of vitamin A and 11 units of vitamin B. Food F1 costs 60/Kg and Food F2 costs 80/kg. Food F1 contains 3 units/kg of vitamin A and 5 units/kg of vitamin B while Food F2 contains 4 units/kg of vitamin A and 2 units/kg of vitamin B. Minimize the cost of the mixtures. what is the objective function?
C = 60X - 80Y
C = 60X + 80Y
C = 80X + 60Y
C = 30X + 40Y
Which is the non negativity constaint?
x1, x2 ≥ 0
x1, x2 ≤ 0
x1, x2 = 0
x1, x2 < 0
